For over five years 'One Nut' Air Operated Double Diaphragm Pumps from FPL have been working reliably in the Medicated Confectionery plant at Boots, Nottingham, requiring minimal servicing!

710 Series Pump

Boots Contract Manufacturing at Beeston, Nottingham are the manufacturing arm of Boots the Chemist, with shops in almost every high street across the country! At the Beeston site a wide range of medicinal and personal care products are manufactured under strict hygienic conditions.

Supplied in 1995, a 710 Series 316 stainless steel pump with virgin PTFE elastomers has been transferring the Pastilles Mass from the cooker into the dispensing system, via a holding tank.

The mass consists of sugar, glucose and other additives used in the manufacture of Boots Throat Pastilles. The area in which the pastilles are manufactured is a clean environment and the pumps have to be washed through with water at a temperature of 90º C.

The mass is pumped at a rate of 2,400kg/hr at a temperature of 90º C with a 2-metre head. Another pump from FPL is used to transfer ingredients, primarily Glycerine, into the cooking vessel.

In the Strepsils production area a 2" Hi Flo 710 Series 316 stainless steel pump handles a glucose/sugar slurry with a viscosity of 15,000 centipoise and a suction lift upto 4 metres!

Commenting, Ian McIntyre – Plant Engineer, "We have been very happy with the performance of the Flotronic Pumps, they have worked reliably for over five years and records show we have only had one new set of diaphragms!"
