Drivecase Cartridge

• A two-part epoxy-coated, cast iron drivecase covers the entire hydraulic range.
• Accepts NEMA 56C frame motors to eliminate alignment problems. IEC motor frames are also available.
• Heavy-duty construction delivers strength and durability beyond anything found in its class.

Hydraulic Cartridge

• Reciprocating plunger design features a 3/4" (19mm) stroke length and six interchangeable plunger sizes.
• Field replaceable, three-part plunger seal.
• Internal oil filter eliminates any contaminants from entering the pump's hydraulic system.
• Externally adjustable hydraulic relief valve located at the high point of the hydraulic system incorporates an integral air bleed valve in a relief valve poppet to accurately vent air from the pressurized hydraulic system.
• Mechanical refill valve provides excellent suction lift capability. Pumps high vapor liquids without modification to existing systems.

Liquid End Cartridge

• Hydraulically balanced single diaphragm design, without process side contour plate, permits use in almost any service condition.
• Pumping action is developed by positive sealing ball check valves.
• Optional check valve arrangements (double ball, soft or hardened seats) for special applications.
• Check valve assembly may be rebuilt for economical maintenance.
• Standard wet end materials include 316SS, Alloy 20, Hastelloy®, PVC and Kynar®. Most machineable metallic and non-metallic materials are available.

Stroke Adjuster Cartridge

• Fully adjustable from 0% to 100% of stroke length.
• Micrometer stroke setting readout in 1% increments.
• Easily converted to DURAmatic electronic actuation.
• Fully sealed to prevent atmospheric contamination or oil leakage.
