JK 1220 HN pump 12 liters 200 bar (1450 rpm)

Pump with three integral ceramic pistons and guide pistons with double sliding diameter to increase the life of the oil seals. Pump design with crankshaft made of high-strength steel and supported by two tapered roller bearings: The connecting rods are made of a special bronze alloy with excellent anti-friction and mechanical properties, the head is nickel-plated to ensure greater resistance to chemical agents while the pump body is made of high-strength aluminum alloy by die-casting and with a painting treatment that significantly increases resistance to corrosion. The rear cover of the pump body has been enlarged so as to contain a greater quantity of oil to guarantee better lubrication, furthermore the oil drain plug is magnetic in order to collect and attract all the metal particles deriving from pump wear. moving mechanical parts. The water sealing system has been improved through a Long Life double gasket in which the primary is able to withstand high performance while the secondary effectively prevents leaks.
