ZPU >Grease Pump
The ZPU Lubrication Pump is one of the industry’s popular grease pumps for progressive and dual grease lubrication systems. The maximum pressure could reach 40Mpa.
ZPU grease pump has many flexible uses. It can have a mobile cart, high-pressure pipes, a grease gun, and a power cable. It could be considered a moveable centralized lubrication pump system.
The ZPU grease pump station is particularly effective for progressive lubrication setups featuring lower frequencies, fewer lubrication points, larger lubricant volumes, and easy mobility.
Driven by a gear motor unit, the ZPU Lubrication Pump efficiently delivers grease through a single outlet port. With customizable grease displacement options to match varying lubrication needs, the ZPU pump transfers grease to distant lubrication points, even through narrow lubricant piping.

Lubrication Pump ZPU is a centralized lubrication pump designed for systems with high lubrication frequency, long pipeline lengths, and a maximum working pressure of 400 bar/40 Mpa. It acts as a grease supply device and adjusts the grease discharge according to different lubrication requirements.
- System Composition
- The ZPU lubrication pump can be combined with a mobile cart, high-pressure central unit, grease gun, and wires to form a mobile centralized lubrication pump system.
- The ZPU pump with a cart is commonly used in progressive lubrication systems that require low lubrication frequency, fewer lubrication points, a large amount of lubricating oil, and mobility.
- Drive Mode
- A gear motor unit drives The ZPU lubrication pump, discharging grease from a single outlet.
- It offers various grease discharge options to meet different lubrication needs.
To ensure the regular operation of the ZPU lubrication pump, the following precautions should be observed:
Installation Position
- The ZPU pump should be installed in a suitable working position where the temperature is appropriate, there is little dust, and it is convenient for adjustment, inspection, maintenance, cleaning, and oil injection.
- Ideally, it should be installed at the center of the lubrication system to shorten the pipeline length, minimize pressure drop, and ensure the ZPU pump generates enough pressure to overcome the back pressure at the lubrication points.
Grease Injection
- During the first operation, inject a certain amount of grease to allow the ZPU pump to run for a few minutes, then use the motor pump to inject grease from the inlet.
Motor Reducer Lubrication
- The motor reducer of the ZPU pump should be lubricated with an appropriate amount of molybdenum disulfide oil through the vent plug, and this should be replenished every four months.
Environmental Requirements
- The ZPU pump should be placed indoors. If used outdoors or in harsh environments, protective measures must be taken.

- Compatibility: Suitable for delivering NLGI 0# to 2# grease (minimum penetration of 265 (25°C, 150g) 1/10 mm) or lubricating oils with a viscosity grade greater than N68.
- Design: Electric high-pressure pumps designed for progressive or dual-line lubrication systems
- Pipe Diameter: Allows the use of smaller diameter lubrication pipes to reach farther lubrication points
ZPU pumps are typically installed at the center of the lubrication system to minimize pipe length and pressure drop, ensuring they generate enough pressure to overcome back pressure from lubrication points. They are a reliable solution for high-pressure centralized lubrication systems requiring high lubrication frequency, long pipe lengths, and dense lubrication points.
Yes, ZPU lubrication pumps can be used in mobile applications. They can be integrated with mobile carts, high-pressure hoses, grease guns, and cables to form portable electric lubrication pump units.
- Mobile Cart Use:
- Ideal for progressive lubrication systems with low lubrication frequency, fewer lubrication points, large amounts of lubricant, and where centralized lubrication is inconvenient.
- Allows the pump to be moved to different locations for mobile lubrication of single equipment.
When ordering a ZPU pump with a cart, the required hose and cable lengths must be specified. The working interval of the ZPU electric lubrication pump is very short, but if long-term continuous operation is needed, it should be specified in the order.
