The XD4 is made of TYPIII hard anodized aluminium and carburized carbon steel. It delivers up to 4 gpm (15 l/m) of oil flow and is self-priming. It is quiet running, using Varna’s whisper-vane technology and is for use with non-corrosive fluids such as oils and coolants. It can produce up to 60 psi (4bar) pressure at nominal voltages of 12 thru 24vdc. The XD4 has a permanent magnet motor and can be used in certain continuous-duty applications.

The XD4 is part of Varna’s line of pumps and turnkey controls used in prelube and transfer applications in experimental flight, fuel cell, off highway, oil/gas, over the road transport, rail and power generation.
