LB elastomer coated rotary lobe pump.

The company says the LB pump has been designed from scratch following an assessment of products currently on the market with a view to producing a process quality pump, positioned above the more agricultural designs yet without attracting the high costs of high end products.

The LB range offers a combination of features. Ergonomic rotors designed in conjunction with Universitat Autonoma in Barcelona, maximise the sealing face while allowing the passage of particles up to 50mm in size. The rotors can be coated in NBR (FDA), EPDM and Viton or supplied in AISI-431 stainless steel. Also to be noted is the unique intermediate chamber that isolates the pump head from the gear box, therefore avoiding any kind of cross contamination. AFlow says the pumps utilise robust, high precision gears with self-aligned roller bearings that ensure that the rotary lobes deliver exceptionally high levels of accuracy and efficiency and use a range of process quality mechanical seals.

Lastly, stainless steel axial liners incorporated in the pump chamber protect the pump casing, help to maintain the pump’s performance and are easy to replace, thereby increasing pump life.
