Toro pump ends weeks of trouble for wastewater pumping station
Project Overview
Resilient solution for wastewater pumping station
A Toro progressive cavity pump proves a good replacement for an unreliable self-priming sewage pump.
Same-day emergency installation of a hire pump led to a company-wide adoption.
Ended reliance on wheeled tankers and weeks of pump-related issues.
Resulted in a long-term TOTEX and risk reduction.
Challenge
The existing self-priming sludge pump was frequently breaking down due to the amount of rag and the challenging suction duty at this pumping station.
To remain compliant, this major water company ran tankers 24/7 while engineers attempted to fix the problem.
A hire pump had been put in, but it couldn’t cope with the pressure in the line.
The 1.5km discharge pipe length and variable NPSHa (Net Positive Suction Head available) at this site made life very difficult for conventional wastewater centrifugal pumps.
With pressure mounting to end the noise, costs, and round-the-clock disturbance, the area manager called Atlantic Pumps for ideas.
Solution
Atlantic Pumps immediately dispatched a duty-matched Toro progressive cavity pump from their hire fleet, installing and commissioning it that same evening.
The Toro S50 pump, with its strong self-priming ability, anti-ragging rotation, and large solids passage, restored full pumping capacity, enabling the wheeled tankers to stand down.
Results
This new pump ended the reliance on emergency tankers, removed a maintenance headache and reduced compliance risks
It wasn’t long before the Operations manager was satisfied that the Toro progressive cavity pumps would be beneficial across more of their problematic pump stations.
Within a month of operation, this client, a leading water company in southern England, ordered more Toro pumps.
The design and build of this progressive cavity pump include a number of features:
- Short-pitch rotor/stator creates larger cavities. This results in better solids clearance, lower rotation speed and improved wear-life.
- Robust double Carden jointed shaft increases asset lifetime. Along with reduced downtime and lower OPEX, the cost-benefit matrix scores well compared with other pump options.
- The mechanical seal and rotor/stator interface handles high-pressure discharge and strong suction.
- VSD and NTC/PTC thermistor-compatible motor options.
“We don’t just replace failed pumps, we work with our clients to take resilience and performance to the next level.”
– Mark McCreadie, Atlantic Pumps
