Product catalog summary
Product Overview: The HPU-DA267/4.1 is a double-acting, air-operated hydraulic pump designed for high flow applications such as pressure testing, chemical injection, and hydraulic power. It features infinitely variable output pressure and flow, maintains static pressure without heat generation or power consumption, and is suitable for both oil and water applications.
Key Specifications:
  • Max Rated Output Pressure: 26,700 psi (1,841 bar)
  • Output Per Cycle: 2.0 in³ (33 cc)
  • Max Flow: 328 in³/min (5 litre/min)
  • Max Air Supply Pressure: 100 psi (7 bar)
  • Ratio: 267:1
  • Air Consumption: 120 scfm (3,400 Nl/min)
  • Tank Capacity: 5 Gallons (23 litres)
Seal Options: The pump offers different seal options including Nitrile (Buna-N), Viton (FKM), and Chemraz (FFKM) for the main seal and check valve seals.
Construction Materials: The frame and tank are made of stainless steel, the air motor is anodised aluminium with Nitrile seals, and the hydraulic cylinder is aluminium bronze. The piston is stainless steel with a corrosion-resistant chrome finish.
Connections:
  • Hydraulic Outlet: 9/16” HP(F)
  • Air Inlet: 3/4” BSPP(F)
  • Net Weight: 90 kg (198 lb)
Common Options: The pump can be customized with various options such as ATEX certification, digital or pneumatic stroke counters, isolation valves, relief valves, and more.
Performance Data: The document provides a table correlating air pressure to hydraulic pressure, demonstrating the pump's capability to achieve up to 26,700 psi hydraulic pressure with a 100 psi air supply.
