news item image

Quattroflow, part of PSG, a Dover company has extended its line of single-use pumps with the introduction of its QF30SU single-use diaphragm pump.

With flow rate capabilities ranging from 0.06-30 litres per hour (0.02-8 gallons per hour), the new pump can be used for handling a variety of pharmaceutical and biotech applications that require lower flow rates.

The pumps feature a replaceable polypropylene wetted pump chamber that can be quickly replaced without the need for special tools.

The simple disposal of the pump chamber also removes the need for cleaning and cross-product contamination risk while reducing downtime.

It also features a linear flow performance, is retrofittable to Quattroflow QF150 drives, and has a maximum pressure of 4 bar (58 psi).

The Quattroflow design does not feature a mechanical shaft seal or wetted rotating parts, which ensures total product containment without abrasion or particle generation.

The pumping principle also enables risk-free dry running, low pulsation and self-priming.
