TANDEM PUMPS
Hydraulic pumps are mechanical devices that convert mechanical power into hydraulic energy. They generate flow with enough power to overcome pressure induced by the load. Hidros can provide double and triple tandem pumps with different specifications upon customer request.
HIGH-LOW PUMPS
Many systems require a high volume at low pressure for rapid traverse of a vise or tool, and then low volume, high pressure for clamping or feeding. This can be accomplished by a hi-lo circuit using two pumps.
PUMP SUPPORTS
Pump supports (pump front bearings) are suited to drive hydraulics pumps/motor belts, chain or other transmission where heavy combined loads (axial and radial loads) take place.
PUMP FLANGES
Hidros offer pump flanges for group 1, 2, 3, 10, 20 and 30 pumps with different thread specifications.
-
Straight and 90 degrees elbow types.
-
Light and heavy series.
-
SAE pump flanges.
