EXAMPLE: 50PH23DBCSCDescribes a Series 50 Gear Pump/Motor fitted with a high pressure shaft seal; a displacement of 2.3 cu.in./rev; Bi-directional rotation; SAE ‘B’ 2-Bolt Mount, 7/8” Dia keyed shaft and 1-5/16” UN O’Ring side Inlet & Outlet Ports.
NOTE: Series 50 Pumps only are stocked. Because of the high pressure shaft seal and the dual rotation feature they can be substituted where required for use as motors.When used as a motor a case drain connection is only required when the outlet/return pressure is likely to exceed 250 psi.

NOTE: ABOVE PERFORMANCE FIGURES ARE APPROXIMATE AND ARE BASED ON 2000 PSI OPERATING PRESSURE. OPERATING IN SHADED AREAS IS NOT RECOMMENDED.
FOR DRIVE HP REQUIRED: Multiply flow (gpm) by pressure (psi) and divide by 1714. FOR MAX. PUMP SIZE: (for use with gas engine): Multiply rated engine HP by 1028 and divide by pressure (psi). This gives maximum flow rate (gpm). Select the nearest pump size from the above chart according to drive speed. FOR MOTOR DRIVE TORQUE: Multiply HP by 5252 and divide by RPM.
FOR HYD. MOTOR SIZE: Multiply torque (ft. lbs.) by 88 and divide by pressure (psi). This gives motor size in cu.in./rev. Select nearest motor size from the above chart. For full load starting, use a 10% larger motor size.
HP = GPM x PSI 1714
GPM = 1028 HP PSI
TORQUE = 5252 HP(ft. lbs.) RPM
DISP. = 88T PSI

OIL RECOMMENDATIONS: Premium quality anti-wear type oil with a viscosity between 100 and 200 SSU at operating temperatures. Automatic transmission fluids are acceptable. Do not use synthetic fluids.
FILTRATION: 25 micron filters are required with 10 micron preferred. If pump inlet filters are used, be certain inlet flow is not restricted. Cavitation will severely reduce pump life.
PUMP SPEED/PORT SIZE LIMITATIONS: If pumps are operated at speeds higher than shown below, cavitation and pump damage can occur.
PLUMBING SIZE RECOMMENDATIONS: The following is based on 4 ft./sec. inlet velocity and 15 ft./sec. outlet velocity.

BASED ON INLET RESTRICTION (6” HG MAX. VACUUM)MOUNTING: Pumps an motors may be mounted in any position. DIRECT FLANGE MOUNTING: Mount directly to gear box or engine PTO, carefully inserting shaft and pilot into mating holes. Make certain that shaft size and type matches drive. FOOT MOUNT WITH COUPLING: Excessive wear and reduce life will occur due to misalignment. Minor misalignment can be compensated for by using a flexible coupling. FOOT MOUNT WITH BELT OR CHAIN DRIVE: Excessive wear will occur with misalignment.

Side loads resulting from belt or chain drives should be kept as close to the housing as possible (ie., keep dimen-sion ‘L’ to a minimum). For maximum life, loads should be applied at quadrant ‘A’ for pumps (RH), quadrant ‘B’ for motors (RH), ‘A’ for LH motors, ‘B’ for LH pumps, and ‘C’ for bi-rotational motors.

CROSS GEAR PUMPS/MOTORS
DIRECTION OF ROTATION:Right hand (RH) or left hand (LH) pumps or motors, if oper-ated in the wrong direction, will result in THE IMMEDIATE FAILURE of the shaft seal. Pump and motor rotation is NOT field reversible. Dual rotation (D) units may be operated in either direction.
They also can be operated as either a pump or motor. The correct direction of rotation can be determined by the model number stamped on the front cover.
DRAIN PORT CONNECTION: If the motor outlet port pressure exceeds the rating of the shaft seal (20 psi standard), the drain port must be connected directly to the reservoir. Dual rotation pumps have drain port connections for use as motors.
START-UP PROCEDURES:1. Prior to installation, check pump or motor for possible damage in shipping or handling.2. Install unit, tighten fittings and fill reservoir with clean fluid.3. Fill pump/motor with fluid through drain port connection or inlet port.4. Start engine and run at lowest speed. Check system for air (suction) leaks and oil leaks. (Use a piece of cardboard or wood when searching for possible oil leaks, DO NOT USE HANDS). Bleed air from system if necessary. Operate system at normal speed.5. Gradually increase load to normal, checking for leaks, abnormal noises, binding, etc. Operate system for 15 minutes. Shut off and check filters. Clean or replace as necessary.
MAINTENANCE:1. Clean or replace filters on a regular basis, as necessary.2. Check for presence of water in oil (cloudy or milky appearance) and for presence of air (foamy oil). A rancid odour indicates excessive heating of the oil.3. Check reservoir regularly for proper level. Fill as needed. Repair leaks.
FOR ALL PUMPS AND MOTORS, REFER TO SPECIFIC SPECIFICATION SHEETS FOR ADDITIONAL DATA AND LIST OF OPTIONS AVAILABLE.
NOTE: If chronic shaft seal failure occurs: 1. Check direction of rotation. 2. Check outlet port or drain port pressure. 3. Replace shaft seal with higher pressure rating seal. (See available seal kits)
