Charge pump

Displacement machine, in which two or three screw spindles engage one another such that the edges seal against one another and against the housing. In displacement areas between the housing and the sp

Hydraulic pump — mostly with a single piston — for manual operation. It is single-acting in most cases, i.e. priming occurs during the first section of the cycle and delivery during the second. With d

Special form of internal gear pump , in which no sealing sickle is required, as the seal between the fixed gear ring and the rotor (planetary gear) is directly possible through the suitable design of the

product of the chamber volume, number of gears and rotation speed (Figure Z 1). The accuracy of the gear pump flow meter depends on the leakage in the gears; it is around ±0.5 % of the nominal flow .

Hydraulic pump/motor with two or more gears working together in one housing. They may take the form of an external geared pump/motor , an internal geared pump/motor or an annular gear pump/motor .

External gear pump on which, for reasons of noise reduction, two pairs of gear wheels are used that are offset in relation to each other by half the tooth pitch. In this way the delivery flow pulsation [...] pulsation of, e.g., 14.3 % on a normal pump is reduced to 3.6 % (Figure D 88) .

Variable pump in position " Delivery flow zero". Often, the pressure hold position of the pump, i.e. the position in which the pump covers the leakage losses incurred, is – incorrectly – labelled the pump's [...] pump's neutral position.

pumps the overall pump delivery flow can be adjusted to demand. Digital pumps are only used infrequently these days. Instead the easier to use but also more expensive variable pump is used with a delivery

Hydraulic pump in which the pressure fluid is displaced by one or more pistons . Pistons may be arranged in a row or aligned radially or axially in relation to the drive shaft.
