Hypro Corporation’s Twin® piston and plunger pumps are used in a variety of spraying and pressure cleaning applications, as well as hydrostatic testing. These heavy-duty pumps are ideal for fluid handling of water and nonabrasive or general use chemicals. All pumps are constructed from cast iron materials. They feature stainless steel valves and ball bearing, leather or fabric-reinforced Buna-N or straight Buna-N cups.
In this series of Hypro pumps, the 5321C, 5322C, 5324C & the 53702 are the standard pumps. All other letter codes after these base models indicate a change. For example, a 5321C-H is the same pump as the 5321C except it has a hollow shaft instead of a solid shaft.
H=Hollow Shaft / D=pump with injector head / *=This requires a 'special order' gas engine with a 5/8" shaft
