Efficient mix

Aeropak (Chemical Products) is using three MasoSine sanitary pumps from Watson-Marlow Pumps Group at its new Great Yarmouth site to ensure the efficient mixing of mainly aqueous and oilbased OTC and prescription medicines, moisturising creams, and other dermatological products.

The MasoSine pumps - SPS2, SPS2.5 and MR130 - are also used to transfer product from the mixing vessels into bulk storage containers.

Graham Abraham, projects manager, says it was the gentle, low shear product handling capability of the pumps that underpinned their original selection. This is achieved due to the sinusoidal rotor integral to both SPS and MR series models, which gives a wave-like action. The single rotor design offers low propulsion, while large pumping chambers help preserve and maintain product integrity.
