Quiet Vane Pumps are designed for machine lubrication.

Press Release Summary:

Used for closed loop lubrication systems in open gear drives and similar applications, ML series is built on Whisper Vane pump technology and optimized for machine lubrication. ML-4 can make up to 4.0 gpm, while ML-2 makes up to 2.6 gpm. Both have same dimensions, which facilitates configuration and integration while allowing interchangeable flow rates. Also included, integrated bypass valve can be adjusted 30–80 psi externally while pump is running to set flow as needed in real-time.

New Pumps from VARNA Products for Machine Lubrication

In response to customers seeking a simple way to implement a lube system in open gear drives and similar applications, VARNA Products has introduced a new pump series optimized for machine lubrication. Built on the same “Whisper Vane” pump technology as the popular XD line, the ML series pumps promise to be a great choice for closed loop lubrication systems.

According to Mark Ashurst, “After a number of customers expressed interest in using VARNA’s transfer pumps in lubrication applications, we decided it was time to build something specifically designed for the job.” The ML-4 can make up to 4.0 gallons per minute while ML-2 makes up to 2.6 gallons per minute. Both are the same physical size and configuration making it easy for the installer to integrate the pump into their system with interchangeable flow rates.

The quiet running vane pumps are intended to be a part of a lube distribution system with delivery branches leading to multiple lube points within a machine. When used with sized flow restriction orifices in each delivery tube, the flow rate for each lube point can be easily set and held constant regardless of oil viscosity.

Both pumps also feature an integrated bypass valve that can be adjusted 30-80psi externally while the pump is running. “The valve lets the user set the pump flow as needed in real time,” says Mr. Ashurst.

Other features include: direct-coupled motor for reliability, minimal weight and size, field replaceable seal, SAE straight thread O-ring ports, and a rotatable head for customized installation.
