Portable Pumps

P Series Lightweight Piston-Type Hand Pumps Features: Two-speed operation for reduced operator fatigue (except P-39) 4-way valving on the P-84 and P-464 for operation of double-acting cylinders External load release valve on remaining models for single-acting cylinder operation Internal pressure relief valve for overload protection Large oil capacity to power a wide range of cylinders or tools

ENERPAC piston-type hand pumps are self-contained, lightweight, and easily portable. Each unit consists of a reservoir, manually operated pump, a load release valve, and some models have a built-in relief valve. May be operated in a horizontal or vertical position (pump head down). Single-speed and two-speed models are available.

Models P-142, P-392, P-202, P-141 and P-391 have a relief cap to prevent over pressuring of the reservoir. Models P-18, P-39, P-51, P-80, P-84, P-462 and P-464 have an internal adjustable pressure relief valve. Model P-2282 must use a pressure gauge to prevent over-pressurization. Complete dimensional data will be found in the ENERPAC catalog, available upon request.

Plumbing Recommendations
Up to 10,000 PSI, we recommend high pressure hose or schedule 80 pipe. Beyond 10,000 PSI, steel super-pressure tubing, pipe and fittings or equivalent circuit plumbing must be used.

Model HP Hand Operated Hydraulic Pumps O-ring port to eliminate leakage. Delrin seat to seal between tank inlet and piston reservoir. O-ring outlet check for zero leakage. O-ring seal between tank and casting. Steel ball release valve allows oil to travel to tank and relieves pressure on the outlet line. Every HP is tested for outlet check leakage, double or single pump action and relief setting. Optional horizontal mounting brackets allows for horizontal handle actuation.

SPECIFICATIONS:

• Volume displacement
  • HP22SA - 0.20 in3 (3.3 cm3) (when handle is pulled).
  • HP61DA - 0.60 in3 (9.8 cm3) per full cycle.
  • HP121DA - 1.20 in3 (19.7 cm3) per full cycle.

• Tank sizes
  • 95 in3 (1557 cm3), 80 in3 (1311 cm3), 65 in3 (1065 cm3), and 50 in3 (819 cm3).
  • TL - 2 in. (50.8 mm) tank used with remote reservoir.

• Pressure rating and (standard relief setting).

The Brand, hand operated hydraulic pump comes in three basic models HP121DA, HP61DA and HP22SA. Each one of these models comes with a relief that can be adjusted manually to suit the customer's requirements. Brand has also redesigned the outlet check seat for zero leakage. The zero leak seat was created by utilizing an o-ring seal to replace the steel ball seal. The NT (no tank) option does not have a tank, pressure relief and release valve. To use the NT option the customer must connect the inlet of the hand pump to an external reservoir (external reservoir is not supplied by Brand). The TL (2 in. tank) option has a small tank, pressure relief and release valve. To use the TL option the customer must connect the fill port on the tank to an external reservoir (external reservoir is not supplied by Brand). When mounting the NT or TL option, the pump should be placed below the fluid level of the external reservoir. All standard tanks have a 1/4? NPT filler plug at the top of the tank.
HP22SA - has a single-acting piston that can pump 0.20 in³ (3.3 cm³) per full cycle. The term single-acting means that the piston only pumps fluid when the handle is pulled away from the pump. The piston does not displace fluid when the handle is pushed towards the pump. The pressure rating is higher then the HP121DA because it takes less force to displace the smaller surface area of the piston. This pump is typically used in applications that require low volume displacement and high pressure.
HP61DA - has a double-acting piston that can pump 0.60 in³ (9.8 cm³) per full cycle. The term double-acting means that the piston pumps fluid when the handle is pushed and pulled. The pressure rating is higher then the HP121DA because it takes less force to displace the piston. This pump is typically used in applications that require medium volume displacement and medium pressure.
HP121DA - has a large double-acting piston that can pump 1.20 in³ (19.7 cm³) per full cycle. The term double-acting means that the piston pumps fluid when the handle is pushed and pulled. The pressure rating is lower then the HP22SA and HP61DA because it takes a greater amount of force to displace a piston that has a large surface area. This pump is typically used in applications that require high volume displacement and lower pressure.

HP - EXAMPLES OF COMMON MODEL CODES:
HP22SA50...............0.20 in³ (3.³ cm3) displacement, single acting and 50 in³ (819 cm³) tank.
HP61DA95............0.60 in³ (9.8 cm³) displacement, double acting and 95 in³ (1557 cm³) tank.
