We are Fluid Control Solutions
We specialize in engineered fluid control solutions including design and manufacture of oil pumps and electronic controls for lube and transfer applications.
Products
VARNA Products line of industrial pumps are a unique design called a whisper vane pump. They are positive displacement pumps rather than centrifugal. This makes them great primers and ensures that fluid can never vapor lock and stop moving through the circuit. The Whisper Vane design is also much more efficient than a gear pump for high-flow applications like coolant circulation, yet is it very quiet. The Whisper Vane pumps will lift at least one meter and prime quickly even after being completely drained dry. The pump and motor are directly coupled in a tightly integrated package. This keeps the unit small, making packaging easier and eliminating the downtime and maintenance headache of a traditional soft flex coupling. We build our pumps for a long hard life with zero maintenance.
An Engine Prelubrication system on larger engines protects all critical bearing journals before each engine start. Some engine manufacturers list a prelube system as mandatory equipment for certain engines and recommend them for others but any large engine will benefit from the protection that can only be achieved by ensuring oil is protecting critical bearing surfaces before the engine begins to move. Prelube is especially important after engine service that includes an oil or filter change. A single dry bearing start will lead to progressive bearing failure that will lead to overhaul. Prelube is a low-cost insurance policy for your critical engines.
Circulating pumps move oil through a circuit such as gear train cooling, lubrication, cutting or grinding operations, or heat exchanger. Because circulating applications generally require a higher volume of fluid at relatively low pressure, a good circulating pump design is optimized for efficiency under these conditions.
Transfer pumps move fluid from one location to another such as from one tank to another, fill stations, tank evacuation, load Balancing, or day tanks. Because transfer applications generally require a higher volume of fluid at relatively low pressure, a good circulating pump design is optimized for efficiency under these conditions.
Lubrication is a broad category that includes any applications where a constant fluid supply is required to reduce wear and heat between two parts that run together. Engines, bearings, sliding elements, cutting operations, gear trains, and many other kinds of machines all require lubrication. A pump is a simple and common way to ensure areas of friction receive the lubrication they need. VARNA pumps are used in all kinds of applications, from large vehicles to plant equipment to industrial generators.
Over the years, VARNA products has developed a number of controls for pump applications. Some are specials for a customer that needs something applicable only to them, but most are useful for a wide range of applications. We are now offering these controls to everyone that needs a refined pump control solution with more to come in the future.
Applications
Large Engine Prelube
An Engine Prelubrication system on larger engines protects all critical bearing journals before each engine start. Some engine manufacturers list a prelube system as mandatory equipment for certain engines and recommend them for others but any large engine will benefit from the protection that can only be achieved by ensuring oil is whetting critical bearing surfaces before the engine begins to move. Prelube is especially important after engine service that includes an oil or filter change. A single dry bearing start will lead to progressive bearing failure that will lead to overhaul. Prelube is a low cost insurance policy for your critical engines.
Flow Metering Pumps
If you need to inject a metered dose of fluid into a stream or process, a speed controlled metering pump is a great solution. With its integrated speed control, we designed the TG-300 specifically for precise pulseless control of flow up to 400mL/m. The XD-4 also makes a great metering pump for injecting larger volumes of flow into processes or batches. By adding a variable voltage power supply the speed of the XD-4 can be varied from 4 to .5 GPM Both pumps can be set up for both open and closed loop modes to control flow rate based on a number of process metrics such as stream flow, pressure, temperature, or any other properties that can be measured in real-time.
Transfer & Circulating Pumps
VARNA Products’ XD line of industrial Transfer and circulating pumps are a unique design called a whisper vane pump. They are positive displacement pumps rather than a centrifugal. This makes them great primers and ensures that fluid can never vapor lock and stop moving through the circuit. The Whisper Vane design is also much more efficient than a gear pump for high flow applications like coolant circulation and yet is it very quiet. The XD pumps will lift at least one meter and prime quickly even after being completely drained dry. All running surfaces are nitride hardened steel for long service free life even with very low lubricity fluids. The pump and motor are directly coupled in a integrated package. This tight couping not only keeps the unit small making packaging it easier, but it also eliminates the down time and maintenance headache of a traditional soft flex coupling. These things are built for a long hard life with zero maintenance.
Pressure and Flow Control Valves
Varna makes pressure regulating and one-way flow check valves to complement our pumps. We offer these valves as standalone parts or as part of a complete turnkey kit that can include a pump, hoses and fitting as well as customized valves. Our Pressurematic technology can hold extremely tight pressure control over a wide range of flow and our low loss check valves maximize system efficiency especially with high viscosity fluids such as cold
