Balcrank Panther 5:1 Stub Pump with Bung Adapter and PRV (1130-021)

The Balcrank 1130-021 Panther HP 5:1 Air-Operated Oil Pump is a heavy-duty pneumatic piston pump designed for professional automotive repair shops, fleet maintenance facilities, dealerships, quick-lube centers, and industrial lubrication systems. Featuring a 5:1 pressure ratio, double-acting piston design, durable carbon steel pump construction, and included bung adapter and pressure relief valve kit, this professional oil transfer pump delivers dependable performance for medium-volume, multi-point oil dispensing applications.

Engineered for shops requiring reliable lubricant delivery over longer pipe runs or to multiple dispensing locations, the Balcrank Panther HP 5:1 Stub Pump provides the additional fluid pressure needed to support demanding lubrication distribution systems.

Unlike lower-pressure 3:1 pumps, the Panther HP 5:1 is designed to maintain effective lubricant delivery where longer distribution distances, multiple hose reels, or increased piping resistance create greater pressure requirements.

The pump supports compatible synthetic and mineral-based motor oils, hydraulic fluids, transmission fluids, and gear oils up to SAE 90, making it a versatile choice for automotive and industrial fluid dispensing operations.

At the heart of the Panther HP 5:1 is a precision-engineered mechanical air motor with a dual-port air valve and positive-trip detent spool mechanism. This design helps prevent pump stalling during stroke reversal and supports consistent operation in demanding service environments.

Its nitrided steel pump rod and foot valve provide resistance to wear and corrosion, while the Buna-N seals and factory-applied synthetic grease on internal air motor components support durability and routine maintenance.

The pump also features a 2.5-inch effective air piston diameter, 1/4-inch NPT female air inlet, and 1/2-inch NPT female fluid outlet for integration with compatible compressed air and oil distribution equipment.

According to Balcrank's published specifications, the Panther HP 5:1 operates with 10–150 PSI compressed air, has a rated maximum fluid stall pressure of approximately 760 PSI, and delivers up to 6 GPM free flow under specified test conditions. Balcrank describes the pump as particularly suitable for systems designed around approximately 4 GPM of oil delivery.

The Balcrank 1130-021 includes a bung adapter and pressure relief valve kit, helping simplify installation into compatible bulk oil containers and provide protection against pressure buildup caused by thermal expansion in the fluid distribution system.

Whether you're replacing an aging pneumatic oil pump, upgrading your shop's lubrication equipment, or designing a multi-bay oil dispensing system, the Balcrank 1130-021 Panther HP 5:1 Oil Pump provides a durable, serviceable solution for professional fluid distribution.

Important: Actual dispensing performance depends on oil viscosity, pipe diameter, hose length, operating air pressure, and the number of dispensing points operating simultaneously. Contact SoTex Tools to properly size the pump for your system.

Common Applications for the Balcrank Panther HP 5:1

Automotive Repair Shops: Supply compatible motor oils to service bay hose reels and oil dispensing handles in medium-volume repair facilities.

Small and Medium Dealerships: Support centrally located oil pumps distributing lubricant to multiple service bays and dispensing locations.

Fleet Maintenance Facilities: Provide oil distribution for commercial trucks, vans, delivery fleets, and municipal vehicle maintenance operations.

Quick-Lube Facilities: Deliver compatible engine oil through appropriately sized lubrication piping and hose reel systems.

Heavy-Equipment Service Centers: Transfer hydraulic fluids, gear oils, and lubricants used during construction, agricultural, and industrial equipment maintenance.

Industrial Maintenance Operations: Integrate into centralized lubricant distribution systems that require medium-pressure oil delivery.

Why Choose a 5:1 Pneumatic Oil Pump?

The Balcrank Panther HP 5:1 is designed for fluid distribution applications that require greater pressure capability than lower-ratio lubrication pumps.

Longer Oil Distribution Lines

A 5:1 pump provides additional fluid pressure relative to the supplied compressed air pressure, helping overcome friction losses in longer lubrication piping systems.

Multiple Dispensing Locations

When properly sized, the Panther HP 5:1 can supply compatible hose reels and oil dispensing handles throughout a multi-bay maintenance facility.

Consistent Pump Operation

Its dual-port air valve and positive-trip detent spool are designed to support reliable stroke reversal and reduce pump stalling.

Durable Pumping Components

The nitrided steel pump rod, foot valve, and Buna-N sealing components are designed for professional lubricant transfer applications.

Pressure Relief Protection

The included pressure relief valve kit addresses pressure buildup associated with thermal expansion in closed lubrication distribution systems. Installation must follow Balcrank's specifications.

Important Installation and Pump Sizing Considerations

Proper pump selection involves more than choosing the pump ratio. Before installing the Balcrank 1130-021, review the fluid viscosity, service bay count, simultaneous dispensing demand, pipe diameter, total distribution length, and available compressed air capacity.

The pump, hoses, fittings, meters, reels, and distribution lines must all be rated for the system's potential outlet pressure. Balcrank recommends a minimum 3× safety factor for hose fittings and piping and specifies use of the included pressure relief valve kit to address thermal expansion.

Do not use the pump for flammable fluids. Verify all fluid formulations and material compatibility before installation.
