There are two types of Poly:
a) Standard design: The suction flange is also the fastening flange to the reactor.
b) The Low NPSH design: In this case, the fastening flange is designed as an alifning flange and is seated on the delivery side of the pump. The pump is clamped between the aligning flange and the reactor flange. This design provides an extremly large and shkort suction opening, promotin product flow. The oening can be circular, squate or rectangular.
POLY high-pressure gear pump for the discharge of medium to high viscosity media from the reactor. The extra large inlet opening guarantees an even flow of product to the gearwheels even under vacuum or extremely low NPSH conditions.
Offered with either a round inlet port, by means of which the suction flange of the pump is directly connected to the outlet flange of the reactor or as a low NPSH version, where the pump is connected between the pump and reactor flanges, in order to achieve an even larger and shorter inlet port.
