pto hydraulic pump with reservoir brands

Hydraulic pumps convert mechanical energy into fluid power energy. All hydraulic pumps are positive displacement which means the outlet flow is sealed from the inlet flow. A small amount of fluid is designed to leak internally to lubricate and cool the internal components of the pump. The only function of the pump is to produce flow in a system. Bailey International, LLC provides a wide range of pumps and accessories including clutch pumps, dump, gear, jaw couplers, mounting brackets, pistons, PTO, vane and two stage pumps.

PRINCE PTO HYDRAULIC PUMPS Up to 40 gallons per minute and up to 2250 psi UNIQUE FEATURES: PLUS STANDARD FEATURES: • Self-adjusting wear plates on both sides of the gears. • Proper size hose adapters are provided for inlet ports. • Two outlet ports are provided with a NPT adapter for one port and a plug to seal unused port. • Center section available in high strength aluminum alloy for std. duty cycle or in high strength cast iron for high duty cycle use. • Tractor front end loaders • Pull-type cotton pickers • Cotton balers (module builders) • Reliable • Efficient • Roller Bearings • Run fitted body • Internally splined drive shaft. • High-tensile cast iron end plates. • Slips onto tractor PTO shaft (no gear box required). • Two-bolt installation on farm tractors of all sizes. • Tractors imported without integral hydraulics • Landscape equipment • Rotary mowers • Street Sweepers • Back hoes MODEL FEATURES ALUMINUM CENTER HOUSING • Standard duty cycle • Reduced weight • Smaller housing CAST IRON CENTER HOUSING • High duty cycle • Use in circuits with motors • Better at higher temperatures • Increased wear resistance REAR PORTED • Higher flows • Simplified hose connections • Higher flows at reduced engine rpm as compared to other PTO pumps Prince PTO pumps are specifically designed for PTO drive operation on all sizes of farm tractors. No additional gear box is required. Pumps are mounted by sliding the internally splined pump onto the PTO splined shaft and restraining rotation with a torque arm. See page P6 for the PTO pump torque arm kit. • FILTRATION The pump must be used in a clean system with clean oil. The fluid cleanliness should meet the ISO 4406 17/14 level. As a minimum, 10 micron filtration is recommended. • HYDRAULIC FLUID A good quality mineral base hydraulic fluid with a viscosity in the 70-250 SUS range at operating temperature is recommended. • OPERATING TEMPERATURE Oil operating temperature should not exceed 180°F. If it does, the reservoir may be too small or a heat exchanger may be needed. • SHAFT SPEEDS Prince PTO pumps are designed to operate at up to 110% of standard PTO shaft speeds. Standard speeds are 540 rpm for the 6 tooth shaft and 1000 rpm for the 21 tooth shaft. CATP 3-01-20-01 • CLOSE RUNNING CLEARANCE FOR HIGH FLOW RATE Another feature that contributes to the excellent and long-lived efficiency of the PTO-Series pump is the minimum clearance between the gears and the center housing. Each pump is assembled with zero clearance between the housing and the tips of the gear teeth, then test run until the teeth establish a proper wear path in the housing. The result is a much tighter clearance than found in traditional pumps. • PRESSURE RATING Pumps are designed for 2250 PSI max. relief valve setting. A relief valve, external to the pump, must be provided in the system. • PORTS All pumps are provided with an inlet port adapter (SAE O-ring boss to hose barb) and outlet port adapter (SAE O-ring boss to female pipe thread) sized appropriately for the ports and required line sizes. A steel plug is provided for the second outlet port. • RESERVOIR As a guideline, a reservoir size in gallons should equal the pump output in gallons per minute. A larger reservoir and/or an oil cooler may be needed for high duty cycle applications.
