BI-ROTATIONAL PUMP/MOTOR – DESIGNED TO

MEET BOTH APPLICATION NEEDS OUT OF A SINGLE

UNIT. BI-ROTATIONAL FEATURE REDUCES INVENTORY

REQUIREMENTS EVEN FURTHER.

HIGH GRADE CAST IRON – CASTINGS ARE POURED

FROM HIGH GRADE IRON TO MEET THE HIGH PERFORMANCE REQUIREMENTS FOR

YOUR APPLICATION.

VERSATILE 4-PORT DESIGN – PORTING ON BOTH THE SIDE AND REAR. THIS

GIVES YOU INSTALLATION FLEXIBILITY FOR THOSE TIGHT FITTING CHASSIS HOOK-UPS.

HIGH SPEEDS – HEAVY DUTY ROLLER BEARINGS PROVIDE FOR A BROAD RANGE OF

SPEEDS FROM 600 – 3600 RPM TO MEET THE MOST SEVERE APPLICATION NEEDS,YET PROVIDE LONG PRODUCT LIFE.

HIGH PRESSURES – UP TO 3000 PSI (207 BAR) CAPABILITY FOR SEVERE

REQUIREMENTS.

QUALITY CONTROL – ALL PUMPS ARE 100% TESTED BEFORE SHIPMENT.MANUFACTURING STATISTICAL PROCESS CONTROL (SPC) PROVIDES THE HIGHEST

QUALITY COMPONENT PARTS BEFORE EVER BEING ASSEMBLED INTO A PUMP.

OPTIONS – FIVE DIFFERENT SHAFT TYPES, TWO DIFFERENT MOUNTING FLANGES, AND A BUILT-IN ADJUSTABLE RELIEF VALVE PROVIDE OPTIMUM FLEXIBILITY IN HOOKING

UP TO YOUR POWER SOURCE.

Shaft Torque Limitations The pump input shaft can withstandtorques up to the designed shaft torque limitation (STL). This figureis based on multiplying the pump cu. in. displacement x the pumppressure (IE: D x P ≤ STL). Tandem pumps are two pumps with indi-vidual calculated STLs added together not to exceed limitation figure.Note: Connector shaft STL for the tandem pump is ≤ 16000.

TROUBLESHOOTING GUIDE FOR HYDRAULICSHydraulic analysis and proper repair require the use of a vacuum gauge and pressure gauge for testing.

Possible Pump Trouble Cause Cure

Aeration and Low oil supply. Fill to proper level.cavitation: noisy pump Heavy oil / cold oil / wrong oil. Change to proper oil.

Dirty suction strainer. Clean and replace.Suction line too small. Increase size.Restriction in suction line. Remove and replace.

Pump takes too long to Low oil supply. Fill to proper level.respond or fails to respond Insufficient relief valve pressure. Use gauge to reset pressure.

Pump worn or damaged. Repair or replace.

Oil heating up Contamination in relief valve. Remove.Oil too light. Drain and refill with proper oil.Dirty oil. Drain, flush, refill with clean oil.Oil level too low. Fill to proper level.Reservoir capacity too small. Install oil cooler.Insufficient relief valve pressure Use gauge to reset pressure.or pressure too high.Pump slippage. Repair or replace.

Oil foaming Air leaking into suction line from Tighten all connections.tank to pump.Wrong kind of oil. Drain & refill w/non-foaming oil.Oil level too low. Fill to proper level.Improper tank or reservoir baffle. Baffle correctly.Return line above oil level. Install below oil level.Damaged or worn shaft seal on pump. Replace shaft seal(s).

Actuator slips Contamination damages control Clean out the system.valve and allows check valve to leak.Cylinder or piston packing defective. Repair or replace.Valve is cracked. Replace.Spool not centering. Clean contaminants from valve

or replace.Incorrect oil. Replace with correct oil.Load check stuck. Open.

Use vacuum gaugeto isolate problem

Muncie does not promote specific manufacturers’ brands of oil. Recommendations below are guidelines; consult oil manufacturer for exact application needs.
