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 GPMBoth 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

About VARNA

Who We Are

VARNA Products has been solving challenges in fluid handling for over 25 years. We design and manufacture pumps and electronics under one roof. This tight integration between engineering and in-house manufacturing let us be nimble in development while building quality into everything we do. We love to take on the hardest problems in fluid handling and find the right equipment for the job. With several lines of ready to go pumps and valves plus the ability to customise pumping solutions to your needs, VARNA is the right partner for your hardest fluid control problems.

What We Do

We specialize in designing, manufacturing and supporting fluid management systems. Our depth of experience with integrating pumps and electronic controls makes us the ideal partner for your tough fluid management problems. We can develop pumps, electronics, hose assemblies, metering devices, pressure and check valves, to provide complete, custom product solutions or installation kits integrated into a turn key solution to fit your customer specification.

Why Choose Us

Our customers love our solutions for their simple-rugged-reliability, compact size, easy installation, and competitive cost. To assure quality and consistency, we maintain tight controls over all aspects of the manufacturing process, from engineering and design to assembly training, packaging, and shipping. We deal only with a select group of pre-qualified vendors for the parts we do not make in-house, and all assembly and final inspection is done right here. We utilize Six Sigma methodologies of management, design, manufacturing, and packaging to maintain and refine our processes continually.
