LICION ump safety lock type UH NS15, 25, 30 up to 35 a up to 400 D SHEE - OER RION NU NUL ump safety lock type UH is used to reduce the pressure, relieve the pump during start-up or operation. here is also a possiility of proportional electrically operated setting of pump operational pressure, or selection of one of three pressure sets y means of electrically operated valve. UH lock is used for suplate mounting directly on SE pressure connection of pump in any position. y mounting directly on the pump it ensures low flow resistances in the state of relief, slight transition to the relief state, quick return to the state of high pressure and lower level of sound intensity.
