CPXP™ Axial Piston Pump
Compact. Durable. Efficient.
The CPXP™ axial piston pump is a robust, compact, and efficient seawater and wastewater high-pressure pump designed for small to mid-sized reverse osmosis (RO) systems. Engineered for high-pressure and corrosive media environments, the CPXP positive displacement pump delivers exceptional reliability and efficiency across a wide range of flow rates.
High Performance Pump Solutions
Compact Power, Built to Last
The CPXP pump is ideal for any application where space is limited and high performance is valued. Built from Super Duplex Stainless Steel and advanced polymers, the pump resists corrosion even under harsh feedwater conditions.
Designed for Simplicity
The CPXP pump eliminates oil lubrication, reducing contamination risk and lowering maintenance needs. Its self-lubricating piston design ensures long operating intervals, requiring low maintenance for reliable operation. CPXP pumps can also be easily installed in parallel to achieve higher flow rates.
Reliability You Can Count On
Energy Recovery’s CPXP pumps undergo rigorous four-level quality control, including destructive raw material testing, functional performance testing, and final reliability checks. Certified to ISO 9001:2015 standards, each pump is built to deliver consistent, dependable performance.
PX® Pressure Exchanger® and Turbocharger Pairing
Pairing the CPXP with our PX Pressure Exchanger or turbocharger creates a high-efficiency pumping and energy recovery solution, which reduces the overall specific energy consumption of the RO system. This pairing reduces both operating and capital costs of small to mid-sized RO systems.
