Centrifugal pumps G2-OPG and G2-OPE (special) are designed to pump cheese grain together with whey or water from cheese baths or from cheese makers in forming devices or in the drum for separating whey. The main parameters of the pump are selected taking into account the minimum mechanical impact on the product In order to preserve the structure and shape of the grain, these pumps are designed to create a low pressure and have openings of suction and discharge pipes of large diameters. C. Productivity of this pump reaches 25,0 cubic meters / h at a pressure of 3 meters of a water column.
The design of the G2-OPE pump is quite simple and consists of a motor (AIR100 L6 - 2.2 kW / 1000 rpm), housing, working chamber and legs. The impeller of the G2-OPE pump has five wide blades curved in the opposite direction of rotation and open from the side of the pump cover. The impeller is mounted inside the pump on a tip pressed on the motor shaft and fixed with a nut. In turn, the pump chamber includes suction and discharge pipes with connecting threads of DN80 size (according to DIN 11851). Also included with connecting threads are conical fittings and cap nuts. Also to avoid leakage of the product during pumping, this pump unit is equipped with an end seal type G2, which provides high tightness of the working chamber by means of a special spring. The tightness of the pump is also ensured by a clamp (special fastening between the chamber and the pump housing), which also provides simplicity and ease of maintenance of the food pump G2-OPE. It should be noted that all materials of the flowing part of the pump G2-OPE are made of stainless steel AISI 304 (08Х18Н10) approved for use in the chemical and food industries. The motor is protected from moisture by a casing. The pump is installed without a foundation on three legs.
