Product catalog summary
Product Overview: The HPU-DA33/4.1-N*-L** series 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 oil or water applications.
Key Specifications:
  • Max Rated Output Pressure: 3,330 psi (230 bar)
  • Output Per Cycle: 15.6 in³ (256 cc)
  • Max Flow: 2,127 in³/min (35 litre/min)
  • Max Air Supply Pressure: 100 psi (7 bar)
  • Ratio: 33:1
  • Air Consumption: 120 scfm (3,400 Nl/min)
  • Tank Capacity: 5 Gallons (23 litres)
Seal Options: The product offers different seal options including Nitrile (Buna-N), Viton (FKM), and Chemraz (FFKM).
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: The hydraulic outlet is 1/2” NPT(F) and the air inlet is 3/4” BSPP(F). The net weight of the unit is 90 kg (198 lb).
Common Options: Various options are available including ATEX certification, digital and pneumatic stroke counters, isolation valves, chart recorders, relief valves, and mobility features like wheels.
Performance Data: The document provides a table correlating air pressure to hydraulic pressure, demonstrating the pump's capability to achieve a maximum hydraulic pressure of 3,330 psi at an air pressure of 100 psi.
