According to Doering Company (Clear Lake, MN) the DCHP163 cartridge-style hydraulic hand pump provides high-pressure output with the same level force on both up and down strokes. The innovative cartridge high-pressure hand pump displaces large amounts of hydraulic, water glycol or other fluids faster, with fewer strokes. Requiring less handle force, the DCHP163 is ideal for emergency, primary, backup and hydrostatic testing applications.
Doering’s DCHP163 hand pump is offered in stainless-steel versions. The operating temperature with standard seals is -40°F to 212°F (-40° to 100°C) and up to 400°F (204°C) with fluorocarbon seals.
