PP-Series High Pressure Pumps

Maximator PP Series Air Driven High Pressure pumps are compact, lightweight and feature rugged construction capable to increase pressures from 60 to 58,000 psi.

They are available as single acting with either single or double air drive heads and double acting with single air drive head.

PP4 through PP12 pumps have anodized aluminum bodies and stainless steel plungers. PP22 through PP189 have stainless steel bodies and plungers. All PP pumps have polyurethane seals with Buna “N” O-rings.
All PP series pumps are standard with a bottom inlet. For a side inlet, add – S to the catalog number.
Maximum air drive pressure is 145 psi. These pumps require less drive pressure because the pumps are air driven in both directions with no spring under the piston. This design reduces noise and provides less chance of cavitation.
Minimum air drive pressure 15 psi.
For air control option … add – ACM to catalog number.
PP111 and PP189 pumps are available with a double air drive head. This doubles the effective pressure ratio of the pump providing higher pressure capabilities, or using less air pressure to achieve a given outlet pressure. Add -2 to the catalog number.
The PP22 through PP189 are available with a hand lever …add – HL to the catalog number. With the hand lever option,the pump can be operated manually or with air.
