Italswiss resins pump are able to inject two components polyhurethan resins with 1:1 ratio. The injection pump S-35-PU is pneumatically driven, double acting piston pumps operating according to the pressure intensification principle. The pneumatic pressure is multiplied on the base of the ratio between the pump drive zone (low-pressure) and the high-pressure zone; For the S-35-PU it 34:1.
The low-pressure and high-pressure zones are separated in such a way that if the sealings positioned in the high-pressure zone are not leakproof, the possible looses cannot enter into the low-pressure zone. The piston rods are made of high-tensile stainless steel and boast long service lives. The valve seats are made of wearproof quenched steel and sealings of UHMWPE special material.
