Ground Concrete Pump from EZG: Complete Guide to EZG Hog Pump Concrete Pumping Systems

A ground concrete pump from EZG provides contractors with a practical way to move concrete, grout, mortar, self-consolidating concrete, shotcrete, and other compatible materials directly to the placement area. EZG Manufacturing's Hog Pump® lineup is designed for demanding construction and masonry applications where contractors need controlled material delivery without depending on a large boom pump for every job.

EZG Manufacturing offers several Hog Pump configurations for different aggregate sizes, pumping distances, power requirements, and mounting preferences. The current concrete pump lineup includes the HP-20T4 for mixes containing aggregate up to 3/4 inch and the HP-38 series for compatible materials containing aggregate up to 3/8 inch.

These ground-level concrete pumping systems can be useful for block fills, sidewalks, driveways, hardscape projects, pool construction, shotcrete, grout placement, self-leveling applications, and areas where direct access from a concrete truck is difficult.

What Is a Ground Concrete Pump?

A ground concrete pump is a material-delivery machine positioned at ground level that moves concrete through a hose or pipeline to the placement location.

Instead of moving concrete exclusively with wheelbarrows, buckets, skid steers, or other manual methods, material is fed into the pump's hopper and mechanically pushed through the delivery line.

The hose can then be routed toward the placement area.

This approach is especially useful when concrete needs to reach:

• Backyards

• Block walls

• Foundations

• Sidewalks

• Driveways

• Pool areas

• Hardscape projects

• Elevated placement areas

• Restricted-access locations

• Areas separated from the concrete truck

• Long-distance placement points

The exact capabilities depend heavily on the pump, concrete mix, aggregate size, hose configuration, pumping distance, and application.

What Is an EZG Hog Pump?

The EZG Hog Pump is EZG Manufacturing's line of industrial material pumps for concrete, masonry, and related applications.

EZG says its Hog Pump systems are the result of more than 20 years of design development and are built to handle materials ranging from concrete with aggregate to shotcrete, self-leveling material, and self-consolidating concrete, depending on the selected model.

The current Hog Pump family includes:

• HP-20T4

• HP-38

• HP-38SM

• HP-38SS

The pumps are not identical.

Choosing the correct model depends primarily on the material, aggregate size, required output, pumping distance, and preferred equipment configuration.

EZG HP-20T4 Hog Pump

For contractors who need to pump concrete containing larger aggregate, the HP-20T4 is one of the primary EZG options.

EZG designed this pump to accommodate concrete aggregate up to 3/4 inch.

According to EZG, the HP-20T4 can deliver up to approximately 18 cubic yards per hour through a 2-inch line and pump material as far as 800 feet horizontally and 200 feet vertically, depending on operating conditions and material.

That combination makes the machine particularly useful when material must travel a substantial distance from the pump.

EZG HP-20T4 Specifications

Important HP-20T4 features listed by EZG include:

• Handles aggregate up to 3/4 inch

• 8-cubic-foot hopper

• 2-inch material delivery line

• Up to approximately 18 cubic yards per hour

• Up to 800-foot horizontal pumping distance

• Up to 200-foot vertical pumping distance

• Kubota diesel power

• Reversible S-Tube valve

• Digital monitoring and diagnostic control system

• Optional wireless remote control

EZG specifically identifies applications including block filling, small driveways, sidewalks, pools, skate parks, and sloped stabilization.

Actual production and pumping distance depend on the material and jobsite configuration rather than the machine alone.

Why Aggregate Size Matters

Aggregate size is one of the most important considerations when choosing a concrete pump.

Concrete contains cement, water, sand, and aggregate. The size, shape, grading, and proportion of aggregate influence how easily the mixture travels through a pump and hose.

Trying to force an incompatible mixture through a pumping system can cause:

• Hose blockages

• Material separation

• Inconsistent output

• Excessive pump pressure

• Increased wear

• Downtime

The HP-20T4's ability to accommodate aggregate up to 3/4 inch makes it suitable for applications requiring mixes that would exceed the aggregate capacity of EZG's smaller HP-38 series.

EZG HP-38 Ground Concrete Pump

The EZG HP-38 series provides another approach to ground-level concrete pumping.

These machines are designed around compatible materials containing aggregate up to 3/8 inch.

EZG states that the HP-38 family can handle materials including self-consolidating concrete, lightweight concrete, masonry grout, shotcrete, slurry, and compatible 3/8-inch ready-mix materials.

This makes the HP-38 particularly versatile for contractors working across concrete, masonry, hardscape, and specialty placement applications.

HP-38 Pumping System

The HP-38 differs mechanically from the HP-20T4.

EZG's HP-38 models use a progressive cavity pumping system with variable-speed hydraulics and reversible functionality.

Variable pumping speed gives operators greater control over material delivery.

That can be valuable when moving between applications requiring different placement rates.

Reversible operation is also important because it provides additional control over the material inside the pumping system.

HP-38 Output Capacity

EZG currently lists HP-38-series delivery capacity in the neighborhood of 10 to 15 cubic yards per hour for certain configurations using a 2-inch line, while specific model literature lists output ranges that vary by model and setup.

The important point is that maximum advertised output should not automatically be interpreted as guaranteed jobsite production.

Actual concrete pumping rates can change according to:

• Mix design

• Aggregate

• Material consistency

• Hose diameter

• Hose length

• Vertical rise

• Number of hose bends

• Pump settings

• Operator technique

A pump should always be selected according to the complete application rather than output capacity alone.

HP-38, HP-38SM, and HP-38SS

One advantage of the HP-38 platform is the availability of several configurations.

The HP-38 is available as a towable machine.

The HP-38SM provides a skid-mounted configuration.

The HP-38SS provides a skid-steer-mounted solution powered hydraulically.

EZG specifically lists hitch-mounted, skid-mounted, and skid-steer-mounted options within the HP-38 family.

This gives contractors more flexibility when choosing equipment around their existing fleet.

Towable Ground Concrete Pump

A towable concrete pump can be especially practical for contractors who work at multiple jobsites.

The pump can be transported behind an appropriate vehicle and positioned near the concrete supply when arriving at the project.

EZG's masonry pump lineup includes towable configurations specifically designed for convenient transportation between jobsites.

For contractors who regularly perform smaller concrete placements, grout fills, sidewalks, hardscaping, or other jobs, this can provide an alternative to arranging a large pumping system for every pour.

Skid-Steer Mounted Concrete Pump

The HP-38SS provides a different approach.

Instead of towing a separate engine-powered machine, this configuration can integrate with compatible hydraulic equipment.

EZG lists the HP-38SS as an auxiliary hydraulic-powered model capable of operating with hydraulic flow up to 42 GPM at 2,600 psi in its published Hog Pump specifications.

A skid-steer-mounted pump can be particularly useful for contractors who already transport a skid steer to jobsites.

Equipment compatibility must always be verified before operation.

Concrete Pump for Block Filling

Block wall grouting is one of the strongest applications for a ground concrete pump.

Concrete masonry walls can contain vertical cells that must be filled with grout around reinforcement.

Manually moving material becomes increasingly inefficient as wall length and height increase.

EZG specifically markets the Hog Pump line for filling block walls with grout or pea-rock-type material within the applicable pump's aggregate limitations.

The operator can route the delivery hose along the wall and place material where it is required.

Ground Concrete Pump for Driveways

A compact concrete pump can also be valuable for driveway work.

Direct truck access is not always possible.

The driveway placement may be behind an existing structure, around landscaping, beyond a narrow entrance, or far from the concrete truck's safe operating position.

A ground pump allows compatible concrete to be delivered through hose rather than repeatedly transported manually.

EZG identifies small driveway and sidewalk projects among the applications for its HP-20T4.

Concrete Pump for Sidewalks

Sidewalk placements often involve long, narrow work areas.

A concrete truck may only be able to access one portion of the project.

Running a pump line along the placement area can help contractors put material closer to the finishing crew.

This can reduce the amount of manual transportation required and help maintain a more consistent material-delivery process.

Concrete Pump for Pool Construction

Pools create particularly challenging material-placement conditions.

Backyard access may be limited, and the concrete truck can be located a considerable distance from the work.

EZG specifically identifies sloped stabilization associated with pools and similar applications for the HP-20T4.

HP-38-series equipment can also serve hardscape applications involving poured features and pool coping when the material specifications are appropriate.

Pumping Shotcrete with an EZG Pump

Certain EZG Hog Pump configurations can handle shotcrete applications.

EZG lists shotcrete among the compatible applications for its HP-38 series.

Shotcrete applications require proper material preparation, pumping equipment, delivery components, and experienced operators.

Contractors should confirm that the complete system—not simply the pump—is configured for the intended material and placement method.

Pumping Self-Consolidating Concrete

Self-consolidating concrete, commonly called SCC, is engineered to flow into forms and around reinforcement with minimal mechanical consolidation.

EZG identifies SCC as one of the materials that can be handled by its HP-38 series.

This capability can make the same pump useful across several types of specialized construction work.

Pumping Grout and Mortar

One of the defining advantages of the Hog Pump line is material versatility.

EZG describes the equipment as a triple-use system capable of handling concrete, grout, and mortar, with exact capabilities varying by model.

A contractor performing both masonry and concrete work may therefore be able to use the equipment for several revenue-producing applications instead of dedicating it to only one type of material.

8-Cubic-Foot Hopper

The HP-20T4 and HP-38-series pumps use an 8-cubic-foot hopper according to EZG's current specifications.

The hopper receives material before it enters the pumping mechanism.

Proper feeding is important.

Operators should prevent foreign objects or oversized material from entering the hopper and must keep guards and safety equipment installed.

EZG's operating instructions specifically warn operators against using equipment with safety grates or guards removed.

Reversible Concrete Pump Operation

Reversible pumping provides an important level of control.

The HP-20T4 uses a fully reversible S-Tube valve, while the HP-38 platform provides reversible progressive-cavity operation.

Reversibility can help operators control material movement within the pumping system.

It should always be used according to the manufacturer's operating instructions.

Wireless Remote Control

EZG offers optional wireless remote functionality on Hog Pump equipment.

Remote operation can allow the pump to be controlled without requiring the operator to remain directly beside the machine throughout placement.

This can be particularly useful when the hose discharge point is far from the pump.

EZG specifically promotes the wireless remote as a way to increase jobsite control and efficiency.

Benefits of a Ground Concrete Pump

The biggest advantage is access.

Concrete does not always need to be placed immediately beside the ready-mix truck.

A properly configured pump can move compatible material through hose to areas that are otherwise difficult to reach.

Other potential advantages include reduced manual material handling, greater placement control, increased productivity, versatility across different applications, and the ability to serve smaller projects where a full-size boom pump may not be the preferred solution.

For contractors performing frequent concrete, masonry, hardscape, or pool work, owning a pump may also provide greater control over scheduling.

Maintaining an EZG Concrete Pump

Concrete pumping equipment must be cleaned and maintained correctly.

Concrete and grout harden rapidly when material remains inside components.

After operation, the pump and delivery system should be cleaned according to the manufacturer's procedures.

Operators should regularly inspect:

• Hoses

• Connections

• Seals

• Hydraulic components

• Pumping components

• Safety guards

• Engine systems

• Hopper

• Controls

EZG provides online operations manuals, parts manuals, and other resources for both the HP-20T4 and HP-38.

Ground Concrete Pump Safety

Concrete pumping creates substantial pressure.

Never disconnect a pressurized hose or attempt to clear a blockage without following the manufacturer's shutdown and pressure-relief procedures.

Operators should use required personal protective equipment and keep hands, clothing, tools, and other objects away from moving machinery.

EZG's HP-38 operating instructions specifically require guards and safety devices to remain in place and direct operators to shut down and disconnect power before servicing or cleaning the machine.
