Description
Solid brass pump impellers and stainless steel pump shafts eliminate corrosion when boosting weak jobsite water supplies. The IMER Spin 15A Water Booster Pump maintains steady water pressure into continuous mixing chambers to prevent dry batch blockages. Contractors spray self-leveling mortar fast. The pump motor requires clean water sources to avoid clogging small internal valves.
Corrosion-resistant stainless steel forms the main pump shaft, while machined brass castings house the internal peripheral impeller. A totally enclosed 0.6-horsepower electric motor operates on 115V single-phase current drawing 5.2 full-load amps. The fluid circuit incorporates an integrated pressure switch and brass check valve to maintain continuous line pressure. Net pump kit weight sits at 24 lbs with exterior dimensions measuring 9 inches wide by 14 inches long by 11 inches high.
Key Features of IMER 1107638
Continuous mixer operators buy IMER 1107638 pump kits when commercial mortar mixer pricing requires constant water pressure on high-rise jobsites. This kit feeds continuous plaster mixers, mortar pumps, grout machines, and self-leveling pumps.
- Corrosion-resistant brass impeller delivers constant water pressure up to sixty PSI.
- Dedicated 0.6-horsepower motor operates on standard 115-volt jobsite power supplies.
- Integrated pressure switch starts the pump whenever the continuous mixer calls for water.
- Stainless steel motor shaft resists pitting from hard mineral jobsite water supplies.
- Brass check valve maintains line prime to stop dry batch surging during restart.
- Quick-connect brass garden hose fittings simplify hookup to jobsite water lines.
- Compact mounting bracket secures directly to the Spin 15A mixer chassis frame.
Booster Pump Bench Hydraulic Diagnostics
Bench testing confirms pump delivery reaches 5.5 GPM at forty-five PSI dynamic head pressure. Shut-off head registers at sixty-eight PSI on calibrated pressure gauges. Motor current draws 4.8 amps during continuous water delivery, peaking at 5.5 amps on cold start line pressurization. Motor shell temperatures level off at 128 degrees Fahrenheit after two hours of continuous pumping. Internal silicon carbide mechanical seals show zero water seepage during twenty-four-hour continuous recirculation testing on shop benches.
Mixer Water System Upkeep Procedures
Direct chassis mounting keeps water lines short to prevent pressure drop into the mixing tube. The automated pressure switch eliminates manual valve adjustments while loading dry bags. Do not buy this pump kit for moving thick slurry, abrasive mud, or petroleum chemicals.
- Clean the brass inlet mesh strainer each morning before starting mixer operations.
- Drain the pump casing during freezing winter weather to prevent cracked brass castings.
- Check electrical connection cords for jacket wear before connecting to power outlets.
