We originally designed XD-4 to circulate thin mineral oil at very high temperature in a cooling circuit for a military armored vehicle application. The challenge of meeting these tough requirements forced us to solve a number of engineering problems, yielding a very hardy and robust pump that makes a great industrial circulating pump. The XD stands for extreme duty. If you have a challenging circulation application, give us a call and put the XD line of industrial circulating pumps to work.
VARNA offers two XD pumps designed for Transfer or Circulating applications, the XD-4 and the XD-9.

VARNA Products' XD line of industrial circulating pumps are a unique design called a whisper vane pump. They are positive displacement pumps rather than a centrifugal, making them great primers and ensuring that fluid can never vapor locks and stops moving through the circuit. The Whisper Vane design is also much more efficient than gear pumps for high flow applications like coolant circulation and yet it is 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 tight integrated package. This 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.
The TG-300 is special because pump speed can be controlled in real time with the integrated electronics attached to the back end of the motor. Because it is a positive displacement gear pump, varying the speed in this way can allow a number of useful processes to be achieved making it great for metering pump applications. The electronics can be set up for either constant flow or pressure or a number of other closed loop processes.
Compact is a design criteria that many pump manufactures ignore as too costly. Varna pumps are small because some of our customers are space constrained, but also because it yields a better pump of any use. By eliminating shaft couplings and extra space Varna pumps are more reliable, easier to install and less costly to ship.
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."
