  • Non-Replaceable Cam: Unlike the CP- and CD-models, the cam is fixed, but the side plates are replaceable for extended service life.
  • Adjustable Internal Relief Valve: Provides precise pressure control for optimal pump performance and safety.
  • Fewer Mechanical Sealing Options: While there are fewer sealing options compared to the CP- and CD-models, the PZ-model still ensures robust operation for suitable applications.

These pumps are an ideal choice for applications requiring durable, high-performance fluid handling in industries such as petroleum and solvents.

  • Flow rates up to 165 gpm (624.5 l/min)
  • Working pressures up to 200 psi (13.8 bar)
  • Differential pressures up to 125 psi (8.6 bar)
  • Temperature range: -25 to 225 °F (-32 to 107 °C)
  • Viscosities up to 20,000 SSU (4,250 cSt)
  • Two Pump Sizes: Available in two sizes to meet diverse operational needs.
  • Low Pressure Capability: Designed for a maximum working pressure of 200 psi (13.8 bar).
  • Six-Vane Design: Ensures smooth, efficient operation with vane drivers for reliable performance.
  • O-Ring Construction: Provides durable sealing and long-lasting reliability.
  • Replaceable Side Plates: The cam is not replaceable, but side plates are reversible and can be replaced for extended service life.
  • Foot Mounted Design: Suitable for both stationary and truck configurations, offering flexibility in installation.
  • Mechanical Sealing: Two sealing options available for adaptable and reliable operation.
  • Connection Options: Available with NPT, BSPT, or weld flanges, with ANSI flange kits also available.
  • Hydraulic Drive Option: Available for applications requiring hydraulic power.
  • Pump Casing and Heads: Made from ductile iron for superior strength and resilience.
  • Side Plates: Constructed from ductile iron for added durability and long-term performance.
  • Rotor and Flanges: Also crafted from ductile iron to withstand high pressures and harsh conditions.
  • Seal Seat: Silicon carbide for excellent resistance to wear and corrosion.
  • O-Rings: Available in Buna-N and Viton®, both offering reliable sealing and resistance to a variety of fluids (Viton® is a registered trademark of DuPont).
  • Blades: Manufactured from advanced polymers to ensure efficient operation and longevity.
  • Self-Adjusting Sliding Vanes: Maximizes pumping performance by automatically adjusting to wear, ensuring consistent efficiency.
  • Simple and Cost-Effective Maintenance: Easily replace the internal components by removing the pump head without disturbing the piping, minimizing downtime.
  • Vapor Handling Capability: Effectively handles small amounts of vapor, ideal for applications involving liquefied gases.
  • Excellent Suction Lift: Provides superior suction lift, making it effective for clearing suction and discharge lines.
  • Internal Relief Valve Options: Comes with a standard internal relief valve or an optional air-operated valve (AOV) for precise flow control at high and low flows.
  • Stainless Steel Internal Relief Valve: Ensures long service life and durability under demanding conditions.
  • Adjustable Internal Relief Valve: Offers flexible pressure regulation for optimal system performance.
  • Aviation fuels
  • Fuel oils
  • Lube oils
  • Solvents
  • Many more light liquids
