What Are Piston & Plunger Pumps?
Piston and plunger pumps are positive displacement pumps that deliver consistent flow and high pressure by using a reciprocating piston or plunger to push fluid through a chamber. Known for their efficiency, these pumps are ideal for high-pressure applications in industrial settings. Cat Pumps’ models are built with corrosion-resistant materials and precision components to deliver extended service life and minimal maintenance—ideal for continuous-use systems.

FAQ: Cat Pumps & Parts
What’s the difference between a piston and plunger pump?
- Piston pumps use a reciprocating piston sealed with rings, while plunger pumps use a solid plunger and external seals. Plunger pumps are better for high-pressure, continuous-duty applications.
Can I use generic parts in a Cat Pump?
- It’s not recommended. Using OEM Cat Pump parts ensures proper fit, pressure retention, and system life. Siewert Equipment stocks all original kits and components.
How often should I replace seal kits?
- Replacement intervals depend on runtime, pressure, and fluid. Typically, every 1,500–2,000 hours. We can help set a maintenance schedule.
Are Cat Pumps good for chemical or corrosive applications?
- Yes. Many models are available in stainless steel or nickel aluminum bronze for chemical compatibility.
How do I choose the right valve kit?
- Each pump model has specific valve kits. Contact us with your model number, and we’ll match you with the correct part.
What lubricant should I use?
- Only Cat Pumps crankcase lubricant should be used—it’s engineered to maintain viscosity and protect internal components under pressure.
Can I run Cat Pumps dry?
- No. These are not self-priming or dry-run capable. Always ensure inlet feed is sufficient and air-free.
Is installation complicated?
- Not at all. Siewert Equipment can assist with installation instructions, drive setup, and system alignment.
Do you offer rebuild services?
- We offer guidance on DIY rebuilds and can connect you with certified service centers if needed.
Do you sell complete pump systems?
- Yes. Motor-pump skids, custom packages, and turnkey units are available.
