a high pressure pump of the positive displacement variety which substantially consists of a powerful electric motor, transmission mechanism and crank mechanism, as well as a pump assembly with a pump block, valves and a number of plungers or pistons
a positive displacement pump which means it delivers variable output in
a type of "entrainment" pump whereby gas entering the inlet is trapped inside and then must be expelled as a separate part of the operating cycle
a type of hydraulic pump which uses cam lobe action against the piston to generate hydraulic fluid flow and lift the implements
Push-pull motion on the handle side of pump body moves a piston which pumps product. Higher output and better lift capability than stroke or lever-action pumps.
A type of hydraulic pump that uses cam lobe action against pistons to generate hydraulic fluid flow for the lifting of implements. Though superior in their characteristics and longer lasting, excessive numbers of parts (meaning expense) limited their use to only a couple of manufacturers.
A positive-displacement pump using one or more reciprocating pistons to force water from the pump chambers.
