In response to customers seeking a simple way to implement a lube system in open gear drives and similar applications, we have 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.
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.
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.

VARNA Products was featured in a recent article that covers the different roles pump play in the mining industry. African Mining Brief is a publication of Group Africa Publishing that covers the unique aspects of the mining industry in Africa including mining activity, new discoveries and recent trends within the industry.
Roger Crabb from Commercial Fleet Solutions sent us a few pictures of a prelube installation he did for one of his customers.
His customer loves the faster starts and knowing that his engine is protected from start-up damage.
The pump is mounted on the right frame rail right behind the steering sector.
He used the Varna SCD control mounted to the firewall to handle the heavy power switching and circuit protection. A push button on the dash near the ignition key runs the pump with only a single ground wire running through the firewall.
If you are looking for an installer that will do a clean install, give Roger a call at 770 856 0263.
Simple is a funny idea when applied to pump design. Many people comment on how simple Varna pumps are. A simple design that also performs at a high level is anything but simple to achieve.
Customer Feedback "I am in love with these pumps. The best feature is that I can dead head the pump and there is no screaming PRV."
