KF gear pumps are used for pumping a wide variety of fluids. KF gear pumps are distinguished especially by their wide range of variants which are assembled as required on the modular principle and also permit subsequent upgrade. The pumps are also suitable for media with low lubricating properties. The KF 32...80 with T-valve comprised an attached pressure control valve with a separate tank connection. By a conformist damping the valve offers a good control characteristic and a good dynamic at a free from vibration operation in all working points of the pump. The standard pump housing sections are of gray cast iron. The valve housing sections are of spheroidal cast iron. The gear units are manufactured from high-strength case-hardening steel, hardened and mounted in pecial multi-compound plain bearing bushes. The standard drive shaft is sealed by rotary shaft lip-type seal. All pump sizes incorporate helical tooth system. This feature combined with special gear geometry, results in low noise levels and reduced pressure pulsation.
