New Mono Progressing Cavity Pump Replaces Decades-Old Pump
A new NOV Mono Compact C progressing cavity pump has replaced a Mono pump that has been operating successfully for over 30 years in a chemical process application. GrowHow, a UK fertilizer manufacturer and chemical process industry supplier, is using the new pump in its fertilizer production process.
GrowHow used the original SH80 pump for demanding effluent transfer duty, but the fertilizer manufacturer was in need of an upgrade. “The original pump was still working well, but unfortunately it had been discontinued, and GrowHow decided to upgrade to the latest pump design,” explains NOV Account Manager Paul Green. “We proposed a Compact C range pump as the most appropriate modern alternative and it proved to be an excellent choice.”
“We needed something which combined excellent suction lift performance with the ability to handle high suspended solids content,” continues GrowHow’s Chris Smith. “It also had to be able to withstand the very aggressive nature of the effluent, so that it could provide us with a high level of reliability. The new pump has fitted the bill perfectly and is providing even better performance than the old SH80 unit.”
The Compact C range pump is being used at the GrowHow production plant in Ince, near Chester. It operates at 245rpm, it can handle 3.25 bar pressure, and it provides a 19 m3/h capacity, thanks to its fixed-speed gearbox. Effluent is transferred over 100m to a holding sump after being drawn from an interceptor pit on a 3m lift, where it can then be used as fertilizer by farmers. The new progressive cavity pump is mounted on a trolley so that it can easily be moved in order to draw effluent from different sump tanks.
The new Mono pump is ideally suited to the fertilizer manufacturer because it can easily handle slurries, viscous, and shear sensitive fluids. The pump is able to operate at low speeds, which ultimately reduces wear on abrasive applications, while its high-pressure capabilities eliminate the need for multiple pumps that operate over long distances.
