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.
