Introduction
The VDS-Y hydraulic lubrication pump is a grease transfer unit driven by external hydraulic power. It adopts a hydraulic motor paired with a gear reducer to drive the main piston for reciprocating linear motion, delivering grease to lubrication points.
Designed for heavy-duty industrial scenarios, this pump supports progressive-feed, single-line and dual-line lubrication systems. It is widely deployed in mining equipment, metallurgical plants, port machinery, construction machinery and power facilities. Optional accessories include follower plate, low-level monitoring device and pressure relief solenoid valve, which expand its adaptability to diverse working conditions.

Features/Equipment characteristics
1.Power transmission chain: Hydraulic motor → gear reducer → reciprocating main piston to realize grease pumping.
2.Follower-plate optional: Constrains grease and improves suction & conveying performance for high-consistency grease.
3.Dual-form low-level warning: Visual mechanical indicator and electric PNP switch for remote monitoring.
4.Pressure relief alternatives: Solenoid pressure relief valve or hydraulic pressure relief valve for grease flow switching during oil return.
Our Advantages
1.Hydraulic power input: Powered by hydraulic motor instead of electric motor, suitable for sites with existing hydraulic power sources, strong anti-vibration performance for heavy-machinery environments.
2.Multi-system compatibility: Works with progressive-feed, single-line and dual-line centralized lubrication systems for flexible project matching.
3.Rich optional configurations: Selectable follower plate improves grease feeding performance; visual + 24 V DC PNP low-level alarm provides real-time grease-volume feedback; solenoid-type or hydraulic-type pressure relief options are available.
4.Wide working temperature range: Operates stably from -40 ℃ to 75 ℃, adapts to cold-region outdoor and high-temperature workshop conditions.
5.High protection grade: IP65 enclosure protects internal components against dust and splash water, fit for harsh field working conditions.
FAQ
Q1: Can this VDS Y pump be used in explosive hazardous areas?
A: No. This product has not obtained certification for explosive risk environments, do not deploy it in flammable gas or explosive sites.
Q2: What grease can be used for VDS Y pump?
A: NLGI 0# ~ 2# grease. For working temperature below 0 ℃, special low temperature matched grease must be adopted. When temperature below 10 ℃, start the pump at low speed (10 15 revolutions) for pre operation.
Q3: What does the red indicator bar mean?
A: When the green indicator bar is replaced by red, the grease level is low. Check the grease volume and perform refilling. The electric PNP output will close under low level status for remote alarm signal.
Q4: What will happen if the pump runs out of grease?
A: Dry running without grease will cause permanent damage to internal pump components. Never let the pump run with zero grease inside the reservoir.
Q5: Which lubrication systems does VDS Y support?
A: It can be applied to progressive feed system, single line system and dual line centralized lubrication system; select corresponding valve and distribution accessories according to system type.
