A large dairy factory required a pump for pumping their trade waste up and out of a sump and into their trade waste treatment plant.
CASE STUDIES
Resin Transfer Pump
A customer required a pump to transfer resin from delivery vehicles to bulk storage tanks. The key requirements were reliability and good suction (as the pump had to be mounted above a bunded area and still be able to pull the viscous resin up and over the wall in order to transfer it to the tanks). The flowrate required was 30,000l/h against a pressure of 2 – 3 bar.
Pumping Molasses With Roper Pumps
Pump & Valve were approached with a requirement to pump molasses at very high flowrates – 1,500l/min for 2 pumps and 900l/min for the remaining 2 pumps.
Pumping Hot Leachate From A Reactor
Pump & Valve were asked to look at an application pumping hot leachate out of a reactor. The application was challenging as the leachate was hot (80°C plus) and as the leachate was from a landfill the chemical composition changed by the month, by the week and by the day! The existing peristaltic pumps were failing as the rubber hoses could not cope with the wide range of chemicals that they came into contact with and the 80°C temperature didn’t help either. Hoses were failing between 1 week and 6 months.
Pumping Golden Syrup With A Twin Screw Pump
The customer approached Pump & Valve with a primary requirement for pumping thick viscous golden syrup from a hopper to a filling machine and also the flexibility to pump to another part of the plant 50-60m away when required. Duty flow 11m³/h and the CIP flow jumped to 20m³/h. Head pressure was 6-8 bar.
