Tank to Tank Transfer for Chemical Manufacturer - Peristaltic Hose Pumps

Case Study Download

Customer: Chemical production company 

Application: Aluminium Sulphate dosing

Equipment Supplied: 2 x 1 1/2" close coupled peristaltic hose pumps

Customer Location: UK

Equipment supplied

2 x 1 ½" Horizontal Close Coupled Peristaltic Pump

  • Model: FMP-40
  • Application: Tank to tank transfer of Aluminium Sulfate with 2-3% solid content
  • Drive Details: 0.55Kw, 3 Phase, 50Hz electric motor, IP55
  • Flow: 1.495 l/h @ 29RPM
  • Discharge pressure: 2 bar
  • Hose:Natural rubber
  • Pump Body: Cast iron with polyester powder coating
  • Connections: Stainless Steel AISI-316


We received an enquiry from a Chemical Production Company in the UK looking to dose small quantities of Aluminium Sulfate containing 2-3% solid content. The fluid was being transferred from one tank to another during a chemical process that was vital for the production of various chemicals at the plant. Due to such low volumes needing to be transferred, the chemical pump had to be able to handle a very low flow rates efficiently

Key Challenges:

Peristaltic Pumps for Chemical Production
  • Extremely low flow rate for batching the fluid
  • Presence of solids within the pumped medium
  • Material compatibility with Aluminium Sulfate


Given the details of the above application, we specified two close coupled peristaltic pumps. Peristaltic pumps are often selected for corrosive fluids as there is only one wetted part, which is the inner tube that we supplied in Natural Rubber for compatibility. As the fluid is only confirmed by the tube’s diameter, the solids present could be handled with ease. 

These peristaltic hose pumps are also able to be slowed down to meet the required flow of the chemical process. Running the chemical pumps at such a low speed would greatly extend the lifespan of both the motors and tubes, making them a low maintenance solution for the Chemical Production Company to deal with. Upon receipt of order, these pumping solutions were manufactured and dispatched to the customer within 5 working weeks which met their project deadline with time to spare, ensuring no delays to production.
