PU-DHDA158

Product catalog summary

Product Overview: The DHDA series is a range of air-operated, high-flow, double-headed, double-acting hydraulic pumps designed for pressure testing, chemical injection, and hydraulic power applications. These pumps offer infinitely variable output pressure and flow, maintain static pressure without heat generation or power consumption, and are suitable for oil or water applications. They are known for their robust construction, ease of maintenance, and low servicing costs.

Performance Data: The maximum rated output pressure is 30,000 psi (2,069 bar), with an output per cycle of 3.4 in³ (55 cc) and a maximum flow of 393 in³/min (6.4 liters/min). The maximum air supply pressure is 100 psi (7 bar), with a ratio of 316:1 and air consumption of 200 scfm (5,664 Nl/min).

Seal Options: The standard seal option (N*) includes PTFE main seals and Nitrile (Buna-N) check valve seals. Other options include Viton (FKM) and Chemraz (FFKM) seals, with the latter having a reduced maximum rated output pressure of 15,000 psi (1,035 bar).

Construction: The air motor is made of anodized aluminum with Nitrile (Buna-N) seals. The hydraulic cylinder is constructed from aluminum bronze, and the piston is made from 17-4PH with a corrosion-resistant chrome finish. Check valves are stainless steel, and pilot air valves feature brass/stainless steel internals with Nitrile (Buna-N) seals.

Connections: Hydraulic inlet is 1/2" NPT(F), hydraulic outlet is 9/16” HP(F), air inlet is 1” NPT(F), and pilot air supply is 1/8" BSPP(F). The net weight of the unit is 69 kg (152 lb).

Common Options: Options include ATEX certification (/A), panel mount digital stroke counter (/F), and panel mount pneumatic stroke counter (/G).

Pressure Data: The document provides a table correlating air pressure with hydraulic pressure, demonstrating the pump's capability to achieve up to 30,000 psi (2,069 bar) hydraulic pressure with a 100 psi (7 bar) air supply.
