NOV Installs Mono Pumps in UK Waste Plant
NOV, known for its progressing cavity pumps and pump parts used in the waste water, chemical, food, beverage, paper, mining, mineral processing, marine, agricultural, and oil and gas industries, has provided a major waste recycling plant in Weston-super-Mare, UK with a pair of Mono progressing cavity pumps. The new pumps will help manage 12,000 tons of material each year, which includes 7,500 tons of food waste.
Cory Environmental, a UK waste management company, is using an EZstrip transfer pump and a Compact C range pump from NOV’s line of Mono pumps in its anaerobic digestion (AD) process. It’s no surprise that the waste management company chose NOV pumps for its AD process because three other EZstrip pumps were previously installed in other parts of the plant and have been performing consistently for years.
“Our existing Mono equipment from NOV had performed well, and that was a major factor in our decision to use two additional Mono pumps to handle the depackaged organics which go into our AD process. This is mainly food waste which can be quite aggressive on the rotors and stators of any pumps involved, so it was also important that we chose equipment that we knew would deliver in this sort of demanding application,” says Alistair Holl, director of Cory Environmental Resource Management.
NOV’s EZstrip pumps are able to reduce the typical day-long PC pump maintenance operation that’s needed with other pumps to just 30 minutes with their unique maintenance-in-place design. By reducing maintenance operations, the pumps are able to process more material and ensure that waste recycling employees don’t spend a lot of time fixing equipment. “The time and cost savings that the EZstrip design offers were also major considerations in our decision to use NOV again,” adds Holl.
