'One-Nut' Pumps Prove Essential for Lionel Hitchin

Back To Applications ¦  Printer Friendly

As a result of seeing an advert for the 'One-Nut' pump from Flotronic Pumps Ltd, Lionel Hitchin (Essential Oils) Ltd were impressed with the simplicity of the design and purchased two of their New Award Winning Slimline Super Model pumps to handle Terpenes.

Slimline 316 Stainless Steel Pump

Lionel Hitchen (Essential Oils) Ltd manufactures natural concentrated oils, steam distilled oils, alcoholic extracts, flavours, oleoresins and dispersed herb and spice extracts. The company is a leading supplier to the food, beverage, toiletry and cosmetic industries as well as the flavour and fragrance houses.

Because of the success of the first two pumps they purchased a further FPL 1½" Slimline 316 Stainless Steel Air Operated Double Diaphragm pump fitted with virgin PTFE diaphragms to load liquid raw material and flavourings into a steam heated mixing vessel.

Sucking either from 1000 litres IBC’s or 200 litre drums with a lift of 1.5 metres, the media is then pumped into the top of the mixing vessel, a height of 4 metres. The viscosity is typically around 500 cp’s at ambient temperature.

The pump is fitted with a batch counter which regulates the number of pump cycles to achieve pre-determined quantities of product. Cleaning is critical, so the New Slimline pumps are ideally suited because they are machined from solid 316 Stainless Steel, with no welds and designed to be self draining, which reduces product residue. They have no ball valve seats, resulting in a more hygienic crevice free design.

Recently voted winner at the Food Hygiene Event for 'Hygiene in Food Processing and Manufacture', sponsored by Diversey Lever.

"Flotronic Pumps were selected" comments Chris Dimmick - Engineering Manager at Lionel Hitchen "because I like the ease of stripping, they have food industry approval, were competitive and are of UK manufacture."
