Introduction

The WDS-I Electric Grease Pump is a piston-type lubrication pump available with 1 to 5 oil outlets. Each oil outlet can be connected to either a progressive distributor or a resistance connector. It is suitable for outdoor and field operations, with water-proof and dust-proof performance.
The pump supports multiple power supply options. Models with DC24V, AC220V, or three-phase AC380V can be equipped with a built-in programmable controller to set the pump's run time and pause interval.
A low-oil-level sensor is available as an option. The controller comes with a forced start switch, which allows manual pump activation regardless of programmed cycle settings.

FAQ

Q1: What is the waterproof and dustproof rating of the WDS-I automatic grease pump?

The standard model is rated IP65, which is dust-tight and protected against low-pressure water jets. For customers with higher protection requirements, we can provide customized protection solutions.

Q2: What can the programmable controller do?

The controller allows you to set a single run duration, stop interval, daily or weekly cycle times, and cumulative operating time. This enables timed and metered lubrication for fully automatic management.

Q3: What is the forced start switch used for?

The switch enables manual pump start independent of the controller. It is mainly used for system commissioning, pipeline air purging, manual emergency greasing, and backup lubrication in case of controller malfunction.
