Application Details

One of our customers in the Pharmaceutical Industry needed 3 off safe, simple, accurate and mobile solutions for dosing a reagent (98-100% H2SO4 & Toluene at Ambient Temp) onto their process across a flow range of 23-138 l/hr with a max rated pressure of 10 Bar.

The customer specified that the only approved wetted materials to be used were Hastelloy C-276 & PTFE, and that the pump also needed to be suitable for a Nitrogen Injection Clean Through (2 Bar through suction side of the pump) and fitted with Tri-Clamp Connections on the suction & discharge. The pump sets also needed to be fitted to hygienic trollies and suitable for use in an ATEX Zone 1 environment.

Following conversations about the pump, our team were able to provide the client with a complete turnkey trolley package that included a drip tray, custom suction & discharge adaptors, and pump risers.

Solution & Support Offered

We worked with the customer on designing a bespoke trolley size that fitted their requirements, as per the initial design example pictured. Once approved by the customer, we then put all 3 packages into production and mounted all the equipment at our facility in Southampton before final shipping onto the customer so they had ready to use systems straight out of the box.
