Comet LWS 3525 S Triplex Pump – 2500 PSI, 24mm Solid Shaft, 1750 RPM

Comet LWS 3525 S professional triplex plunger pump for compatible pressure-washing, carpet-cleaning, truckmount and industrial cleaning systems. This heavy-duty pump features a brass manifold, ceramic plungers and a reversible 24 mm solid crankshaft for flexible right- or left-hand drive installation.

This pump is commonly researched as a replacement for HydraMaster 000-111-042 and several related Comet, Kärcher and OEM reference numbers. Because manufacturers may use different fittings, manifolds, shafts, pulleys and mounting configurations, always compare your existing pump before ordering.

What You Receive

• One Comet LWS 3525 S pump assembly

Not included unless expressly shown and stated: pulley, electric clutch, mounting bracket, unloader, regulator, pressure gauge, hoses, fittings, couplers, motor, engine or installation labor.

Before Ordering

1. Locate the model and part number on your existing pump.
2. Measure the crankshaft diameter and usable shaft length.
3. Confirm whether the shaft must extend from the right or left side.
4. Confirm the pump operates at no more than 1,750 RPM.
5. Compare the mounting-hole pattern and crankcase dimensions.
6. Verify the inlet and discharge thread types.
7. Confirm that your motor or engine provides adequate horsepower.
8. Determine whether your application requires standard or high-temperature seals.

Frequently Asked Questions

Does this pump include the motor or engine?
No. This listing is for the pump assembly unless another component is specifically identified as included.

Does it include the pulley or electric clutch?
No. Drive components are normally sold separately. The pulley or clutch must match the 24 mm pump shaft and the equipment’s required operating speed.

Can I operate the pump faster than 1,750 RPM to obtain more flow?
No. Do not exceed the manufacturer’s maximum pump speed. Excessive RPM can damage seals, valves, bearings, plungers and other internal parts.

Is this a direct replacement for HydraMaster 000-111-042?
It is commonly cross-referenced to that number, but installation details can vary. Compare the shaft, mounting pattern, ports, fittings, pulley alignment and operating specifications before ordering.

Can this pump handle hot water?
Temperature capability depends on the exact factory configuration and seal package. Do not assume that a standard LWS 3525 S includes the optional hot-water seal package. Confirm the supplied Comet part number when high-temperature operation is required.

Does the pump arrive ready to operate?
Inspect the pump and verify the crankcase oil level before startup. Proper inlet-water supply, alignment, belt tension, unloader adjustment and installation are required. Never operate the pump dry.

Installation and Operating Notes

• Installation should be performed by a qualified technician familiar with high-pressure pump systems.
• Flush debris from supply hoses and plumbing before connecting the new pump.
• Provide an unrestricted water supply with adequate flow.
• Never allow the pump to run without water.
• Do not exceed the rated pressure, RPM or temperature.
• Align pulleys carefully and avoid excessive belt tension.
• Use an appropriately sized unloader, regulator and pressure-relief system.
• Check the oil level before initial use and maintain the pump according to the Comet service schedule.
• Protect the pump from freezing. Freeze damage is not a manufacturing defect.

Images are for identification and reference. Product appearance, labels and minor components may change without notice. Specifications and OEM associations should be verified before installation.
