Khoday hydraulics manufactures variable displacement pumps under the name var-spe. The company claims these pumps to be the most innovative solution for the concept of radial pistons. The var-spe variable displacement pumps are available in aluminium housing with highly resistant cast iron made inside body. The variable displacement pumps offer a better reliability and higher efficiency. The company provides var-spe variable displacement pumps with accessories to control and adjust speed like manual, electric, electronic, electro-hydraulic, proportional pneumatic, soft start or constant power-winders. The hydraulic variable displacement pumps are useful for applications requiring up to 1800-rpm variable flow rate in both directions as well as power from 0.55 kw to 5.5 kw. These var-spe variable displacement pumps are available auxiliary system as standard fittings with built-in check valves, relief valves and charge pumps for closed circuit working, input male shaft or a hollow shaft. These pumps are ideal substitute for precision operations at medium powers. Some of the technical features of the var-spe variable displacement pumps are wide range of speeds and torque controls, and inbuilt small tank in nine different sizes from 2.1 to 2.6-cm3/rev displacements and up to 300 bar peak pressures.
