F/FP 427 Sanitary Barrel Pump


Harco offers the completely dismountable FLUX F/FP 427 FOOD sanitary barrel pump without mechanical seal that works based on the principle of an axial-flow propeller pump. Its pump unit consists of drive motor and pump. Via a clutch, the motor drives the drive shaft which has a propeller-like impellor attached to its end. Delivery by the pump requires that the impellor is completely covered with the fluid. The fluid is transferred axially due to the rotation, i.e., towards the pump discharge along the pump shaft.

In the seal-less FLUX F/FP 427 FOOD barrel pump, the fluid is transferred along the shaft and also gets into the inner tube where it has the same level as in the barrel. When the barrel is emptied, the fluid level in the barrel is lowered. Accordingly, the fluid level in the inner tube is also lowered and the fluid inside is discharged through the relief openings.

This barrel pump F/FP 427 from FLUX is ideal for hygienic applications and suitable for conveying media out of drums, totes, IBCs and other containers. The drive shaft, the inner and the outer tube are made of stainless steel (316 Ti resp. 1.4581). Pumps are also available in FOOD/FDA and 3A Certified version and complies with international safety standards. These pumps are especially designed to meet the specific requirements of the food, cosmetic and pharmaceutical industries. Models can be used in mobile and fixed installations.
