A two-cylinder pump for heavy flowable material comprising a pump body with a deck surface, a pair of cylinder bores opening at the deck surface, and a piston reciprocating in each cylinder bore in charging and discharging strokes. The pump further includes a valve conduit with an inlet port for the transfer of flowable material between the valve conduit and the cylinder bores, the valve conduit being pivotable about an axis to cause a movement of the inlet port across the deck surface between two operative positions, in each operative position the inlet port being in register with either one of the cylinder bores. A fluid operated piston-cylinder assembly is operatively mounted between the valve conduit and the pump body in order to produce a force with a direction generally coincident with the pivotal axis on the valve conduit for urging the inlet port thereof in sealing engagement with the deck surface of the pump body.
