PUMP AS-WATER 1347613 - Caterpillar

Table 4
Part Number 378-2807
Pump Rotation CW
Step 1 2 3 4
Input Speed RPM 800 1200 1200 1200
Discharge Pressure kPa (psi) 3200 (470)(1) 3200 (470)(1) 3200 (470)(1) 32500 (4800)
Discharge Flow lpm (gpm) 0 1 (0.26)(2) 93.5 (25) 93.5 (25)
Displacement Control Current mA 0 830 1550 1550
Control Cutoff Current mA 0 940 940 940
Pump Loss lpm (gpm) Subtract the actual measured discharge flow in Step 5 from the actual discharge flow in Step 3. The difference is the total loss. 7 (2)
Charge Relief Pressure kPa (psi) 3200 (470) 3200 (470) 3200 (470) 3200 (470)
(1) Discharge pressure equal charge pressure.
(2) This value is for reference. Discharge flow should indicate start of control.
