Imer Spin 15A Water Pump Kit

Features

• Optional water booster pump kit for the IMER Spin 15A Continuous Mixer
• 100% Imer production. Made in Italy

The Imer Spin 15A Water Pump Kit is an optional water booster pump kit designed specifically for the IMER Spin 15A continuous mixer to ensure a steady, adequate water supply when the jobsite water pressure or flow is not sufficient. Labeled as part number 1107638, this IMER‑built kit allows the Spin 15A mixer to draw water from a tank or to boost low mains pressure, helping you maintain consistent mix quality for premixed plasters, mortars, stuccos, grouts, self‑leveling underlayments, and floor screeds.

Overview of the Imer Spin 15A Water Pump Kit

The Imer Spin 15A Water Pump Kit (1107638) is described by IMER and distributors as an “optional water booster pump kit for the IMER Spin 15A Continuous Mixer” and as the “Spin Continuous Mixer Water Pump Kit” for the Spin 15 family. It is intended to be installed on the Spin 15A when:

• Jobsite water supply cannot reliably provide at least 20 l/min at 2 bar.

• You need to supply the mixer from a tank, tote, or cistern rather than direct mains.

Without a booster pump, IMER’s manual states that when the Spin 15A is run as a horizontal mixer without water pump, the water mains must guarantee a minimum flow rate of 20 l/min and minimum pressure of 2 bar. The optional water pump kit solves situations where that is not possible by providing a self‑priming pump and dedicated water circuit components for the mixer.

Key Features and Technical Details

IMER’s Spin 15A documentation and reseller listings highlight several important features of the Spin 15A Water Pump Kit:

• Part number: 1107638 – Spin 15A Water Pump Kit / Water Booster Pump Kit.

• Function: Optional water booster pump for the IMER Spin 15A continuous mixer; also serves as a replacement for the standard pump on pump‑equipped versions.

• Power: 110V (115 V) water pump kit for the 115V Spin 15A mixer, with pump motor around 0.45 kW per Spin 15 specs.

• Pump type: Self‑priming electropump in stainless steel, part of the Spin 15 A’s professional components.

• Maximum pressure: 2 bar at pump discharge (as given in Spin 15 technical data).

• Use cases:

  • Boosting mains water pressure and flow.

  • Siphoning water from a raised tank or container when no pressure line is available.

These details mean the kit is not a generic pump; it is specifically sized and wired to work with the Spin 15A’s electrical and hydraulic system as either a factory‑style or retrofit solution.

How the Spin 15A Water Pump Kit Works with the Mixer

The Spin 15A is a continuous cycle mixer for premixed products in bags, designed to mix dry bagged materials with water and discharge them at a controlled rate. The Imer Spin 15A Water Pump Kit integrates with this process as follows:

• The water pump kit is connected to the Spin 15A’s 1/2" water connection and controlled by the mixer’s panel and solenoid valve.

• The self‑priming electropump draws water either from low‑pressure mains or from a raised water tank via the supplied hose.

• Water passes through a double filtering system and a water flow descaling regulator before reaching the mixing chamber.

• A quick‑acting solenoid valve and micrometric flow regulator on the mixer allow you to adjust water flow to achieve the desired material consistency while the mixer runs.

IMER notes that the Spin 15 A’s “professional components” include a self‑priming electropump in stainless steel, a water flow descaling regulator, a quick‑acting solenoid valve, a double water filtering system, and a drainable antifreeze system when fitted with the water pump kit.

With the kit installed, the Spin 15A no longer depends solely on building water pressure; instead, it can self‑feed from a tank or low‑pressure source, maintaining consistent flow for mixing.

When You Should Use the Imer Spin 15A Water Pump Kit

According to IMER’s Spin 15 manual and distributor descriptions, the water pump kit is recommended when:

• The site’s water pressure is inadequate or unstable.

• The mixer is being used in locations without direct pressurized water lines (e.g., new construction, remote areas, inside structures under renovation).

• You want to feed water from a portable tank or IBC tote rather than depend on building supply.

• You need to meet 20 l/min at 2 bar requirements but only have low‑flow or long‑hose connections available.

PHP Distribution and EquipSupply both note that this kit is used “to boost water flow to the mixer or siphon from the tank” and is an “optional accessory for the Spin 15A and also a replacement for the standard pump on the Spin 15A mixer.”

Master Wholesale lists the Spin 15A’s “standard water pump” as optional and then lists “Water kit – when the water supply is inadequate” as optional equipment, referring to this 1107638 pump kit.

Benefits of the Imer Spin 15A Water Pump Kit

Adding the Imer Spin 15A Water Pump Kit to your continuous mixer provides several practical benefits for mixing and production quality:

1. Reliable water supply and pressure

   • The booster pump ensures that the Spin 15A receives adequate flow and pressure even when the site’s water mains do not meet IMER’s 20 l/min at 2 bar minimum.

   • This reduces mixer stalls or inconsistent water dosing caused by low pressure.

2. Consistent material consistency

   • With stable water flow, adjustments made via the micrometric flow regulator on the Spin 15A are more reliable, yielding consistent mix consistency across many bags.

   • This is important when mixing self‑leveling underlayments, pre‑blended plasters, or structural grouts that must meet manufacturer water‑ratio specifications.

3. Increased jobsite flexibility

   • The ability to pull water from a raised tank or tote opens up more job setups: remote areas, upper floors, or sites without permanent water lines.

   • You can pre‑stage water tanks near the mixer to reduce hose length and pressure losses.

4. Integrated, OEM design

   • The kit is 100% IMER production, made in Italy, and designed to integrate with the Spin 15A’s electrical system, water injection point, and control logic.

   • This minimizes compatibility issues and ensures proper safety and performance.

5. Replacement option for worn pumps

   • For Spin 15A mixers originally supplied with a standard water pump, the 1107638 kit is also used as a direct replacement when the original pump fails.

Typical Applications with the Spin 15A Continuous Mixer

The Spin 15A is often teamed with IMER spray and grout pumps for semi‑automatic production of various materials. It is ideal for quickly mixing:

• Pre‑blended plasters and mortars.

• Stucco and façade coatings.

• Grouts and repair mortars.

• Self‑leveling underlayments and floor screeds.

When used with pumps such as the Mighty Small 50, Koine series pumps, or other IMER spray/grout machines, the Spin 15A acts as a dedicated, continuous mixer feeding pump‑and‑spray systems. In these setups, reliable water supply is crucial, making the water pump kit an important accessory whenever site water can’t be trusted to maintain flow and pressure.

On high‑rise and interior jobs, contractors frequently rely on portable water tanks and booster pumps instead of building water, which is exactly what the Spin 15A Water Pump Kit enables.

Installation and Operation Notes

While IMER’s full installation instructions are in the Spin 15 manual, a few key points from the technical documentation include:

• When using the water pump kit, the maximum inlet water pressure should not exceed 5 bar to protect the pump and mixer water circuit.

• If the mixer is equipped with a water pump and the pump is not fed by water (running dry), the sealing gasket can burn, so proper priming and filter inspection are important.

• The kit’s self‑priming capability allows drawing from a raised container, but the pump still needs the intake filters kept clean and intake hoses free from kinks to ensure sufficient flow.

These operational details help maintain pump longevity and consistent mixer performance.

Why Choose the Imer Spin 15A Water Pump Kit?

The Imer Spin 15A Water Pump Kit (1107638) is the right choice if you operate an IMER Spin 15A continuous mixer in environments where water pressure is unreliable or where you want to supply water from tanks rather than mains. As an OEM optional water booster pump kit, it integrates directly with the Spin 15A’s water circuit, using a self‑priming stainless‑steel electropump, regulators, and filters designed for professional premix mixing applications.

By ensuring adequate, consistent water flow and pressure, the Spin 15A Water Pump Kit helps you maintain uniform material consistency, extend jobsite flexibility, and protect your mixer investment—whether you’re mixing stucco, mortar, grouts, self‑leveling underlayments, or pre‑blended screeds in demanding construction environments.
