ZPU Series Electric Lubrication Pump - ZPU-08

ZPU Type Electric Lube Pump (40MPa)

I. Terms of Use

The ZPU type electric lubricating pump is suitable as a lubricant supply device for single or double-line centralized lubrication systems with high lubrication frequency, long piping lengths, dense lubrication points, and nominal pressure of 40MPa. It can also be equipped with a mobile trolley, high-pressure hoses, grease guns, and cables to form a portable electric lubricating pump unit, used for mobile lubrication on single machines with low lubrication frequency, few lubrication points, large oil supply, and不便采用集中润滑。

This pump is an electric lubrication pump driven by a reduction motor, featuring a single outlet for discharging lubricant. It comes in three displacement sizes, allowing for conveniently assembling the lowest-cost centralized lubrication system to meet various needs; the dry oil centralized lubrication system it forms has the characteristics of long conveying distance and small supply pipe diameter.

II. Technical Specifications

Use grease with a penetration not less than 265 (25°C, 150g) 1/10mm (NLGI 0#-2#) and a viscosity grade greater than N68.

V. Instructions for Use

1. Should be installed in an environment with suitable temperature, minimal dust, and easy access for adjustment, inspection, maintenance, cleaning, and re-greasing.

2. Position as centrally as possible within the system to minimize piping length, maintain the lowest pressure drop, and enable the pump to generate sufficient pressure to overcome the lubrication point back pressure.

3. Prior to first use, add a sufficient amount of lubricant, run the pump for a few minutes, and then use an electric oil pump to add lubricant via the replenishment port in a sealed manner.

4. After the initial three months of use, the motor reducer must be topped up with an appropriate amount of 3# aluminum sulfide lubricant through the exhaust plug hole. Subsequently, top up every four months.

5. This pump is designed for indoor installation. Protective measures must be taken when used outdoors or in harsh environments.

Section 6: Order Instructions

1. When ordering an electric lubrication pump with a trolley, the required hose length and cable length must be specified in the contract.

2. The electric lubrication pump is designed for intermittent operation. If the user requires continuous operation over an extended period, please specify in the contract.
