OPERATING DATE

Piston Pumps - 26224 KCL

NOTES ON PUMP INSTALLATION

1.Recommend a flexiblecoupling to connect the drive shaftand pump shaft so that minimum radial and thrust loads areappliedto the pump shaft.2.Use good quality petroleum fluid. The fluid viscosity should be 20~200cSt (98~900 SUS). For general use, R&O type andantiwear type of ISOVG32~68 are recommended. The optimum viscosity during operation is 20~50cSt(98~232 SUS).3.Operating temperature range is 5~60 º C(41~140 º F). During startup at temperature below 0 º (32 º F),performwarmup operationsat a low pressure and low speed until fluid temperature reaches 5 º C(41 º F)4.The pump suction pressure should not exceed -0.3kgf/cm
2 (-4.3psi)(the suction port flow velocity less than2m/sec(6.5ft/sec).5.The alignment of the pump shaft with the drive shaft should be within 0.05mm(0.002inch). The eccentric angle should bewithin 1 º .6.Necessitate a suction strainer with a filtering level of 100
µ m(150 mesh). Necessitate a 20
µ m line and magnet filters to extendthe life of the pump.7.Always prevent metal powder or water etc from mixing with hydraulic oil, as such objects may deteriorate oil quality andshorten pump life .Note oil quality at all time. Oil contamination should be kept under NAS class10

NOTICES FOR TUBING AT OIL DRAIN PORT RECOMMENDED DRAIN PIPING SIZE

The pump should be mounted with the drain port at aposition to maintain fluid in the pump case. The drain back pressure should be less than 1 kgf/cm

NOTICES WHEN STARTING PUMP HYDRAULIC FLUID CASE CAPACITY

1. Make certain the pump turns in the direction indicated bythe arrow .2. Before starting the pump, you need to fill oil into the inletport of the pump body is fully filled with clean oil.Oil filling amounts are shown on the right table.3. Entrained air in the pump and piping will cause vibrations.Before starting inch the pump without any load to purge the air.4. If your circuit isdifficult to purge theairat staring,we recommend to use the air bleed off valve in your circuit.

SETTING THE PRESSURE AND FLOW RATE

The flow rate is set at maximum and the pressure is set at minimumat the factory. If required to reset the flow rate and pressure use thefollowing procedure.PRESSURE ADJUSTMENT :Turn the pressure adjusting screw clockwisetoincrease pressure.FLOW RATE ADJUSTMENT: Turn the flow adjustingscrew clockwisetodecrease theflowrate.
