KSB supply pumps to the Renfrew Flood Prevention Scheme on the River Clyde
KSB and Ferrier Pumps Ltd recently continued their long standing partnership working on a flood prevention scheme for Renfrewshire Council. This involved planning and collaboration on the front end design, pump testing, supply, installation and commissioning of all the pumps and ancillary equipment.
The project involved KSB supplying four variable speed submersible pumps from their axial flow Amacan pump range and one variable speed sump pump of type Amarex KRT, to the North Renfrew Flood Prevention Scheme near Glasgow. KSB also supplied the 800mm diameter pump discharge canisters which are currently installed in the Storm Pumping Station situated on the south bank of the River Clyde.
The flood prevention scheme will protect more than 300 homes and businesses in North Renfrew and comprises a 3m high embankment and a new underground pumping station at the Mill Burn at Fingal Road. The embankment, which runs westward for 1km from Ferry Road, provides a barrier against direct flooding from the Clyde. The pumping station containing KSB pumps will ensure that tidal surges on the Clyde do not cause the Mill Burn to overflow and flood local properties.
The pumping station provides a capacity of 5.5m3/s to provide standard protection against tidal flooding from the River Clyde and fluvial flooding from Mill Burn. The pumping station’s maximum flow rate has been specified to cover a 1 in 200 year flood event.
KSB Amacan pumps were chosen for this station as their characteristics ideally suit the transfer of very high flows of water at low heads. KSB’s technically advanced pumping equipment is well-suited for flood control and the Amacan pumps ensure flood-prone areas are reliably drained.
KSB Amacan submersible pumps are typically used in land drainage applications and have a compact and slim design, but are extremely powerful.
The Amacan’s slim design makes the submersible pump ideal for installation into narrow discharge canisters. Ferrier Pumps Ltd carried out the mechanical installation at the Renfrew project site and found the pumps were easy to install as the Amacan pump’s own weight ensures self-centering seating of the O-ring seals in the discharge canisters, a simple but effective design feature.
The Amacan pumps come with bearing temperature monitoring, thermal motor protection and leakage sensor in the motor. They also have a low-vibration hydraulic system and a bellmouth optimised for vortex-free inflow making them an excellent choice for the Renfrew project.
Ferrier Pumps also installed in the main sump chamber a KSB Amarex KRT submersible solids-handling centrifugal pump, specifically manufactured in abrasion resistant materials to remove storm water as well as handling a relatively high concentration of solids in the pump station.
This variable speed pump is used for sump drain down following cessation of a storm event.
KSB have also supplied the pump discharge canisters, which were designed by KSB at their UK Head Office in Leicestershire, and were digitally prototyped and tested using the latest 3D design software. The canisters were manufactured by Powerrun Project Management Ltd of Keighley and each 800mm diameter canister was supplied to site in 3 off individual double flanged sections with a combined weight in excess of 3000 Kgs and an overall assembled length of nearly 10 metres.
Before any manufacturing of products or site work began, a report covering the testing and development work was undertaken on a physical hydraulic model of the proposed North Renfrew Ferrier Pumps Ltd, a KSB distributor in Scotland, carried out the mechanical and electrical installation for George Leslie Ltd who was the main contractor for the £3.6m project. The work was commissioned by Renfrewshire Council as part of the overall £10m flood prevention scheme for the town.
