A submersible pump is a mechanical & electrical piece of equipment which can be completely submerged in water or medium, used to transfer the same liquid from one location to another via a common connecting discharge pipe.
The pump would be electrically rated to IP68 and generally either 110v (portable site units), 230v (domestic/commercial units) or 415v (industrial units).
The pump has the electric motor mounted directed on the pump casing and drives an impellor. There are various different impellor arrangements to suit flow / head characteristics, sewage or drainage water applications and type of application, common ones are:
Channel Impellor (single or multiple) – More efficient, so higher flow and heads achievable from same size motor than vortex. Sometimes lower solids handling or slighter risk of blocking. Better suited to surface water applications.
Vortex impellor – Less Efficient. Generally better solids handling capabilities, lower risk of blocking, so better suited to foul sewage applications.
Macerator Type – Greater efficiency, used on high pressure sewage systems, where the distance to pump is very great and/or existing pipework is small bore i.e 40-50mm. The pump contains an intergal grinder which shreds sewage water and faecal matter to enable it to be pumped in smaller bore pipelines.
Light duty construction – Plastic or polymer, pressed stainless steel, cast iron/stainless i.e single domestic sewage or drainage use.
Pumps can be free-standing with cast moulded feet for stand-alone use within tank, chamber, lightwell or manhole or provided with optional guide-rail pedestal kit which has to be installed within tank and pumps pulled up and down using lifting chains on guide pipes. The later is used more commonly on medium / large applications or where depth of tank may cause unsafe maintenance procedures.
Southern Pump Services install and maintain foul water pumping stations.
Our sewage pumping stations can be either above ground or below ground, and suitable from small domestic applications to large installs.
These submersible pumps are available in 220v or 400v electrical supply, which can be supplied or alternatively installed by our Southern Pump Services engineers.
The Rainharvester system can collect rainwater for use in the commercial [in non-potable applications] for laundry, toilet flushing, general cleaning and watering.
At southern pumps we provide comprehensive after sales support providing a second to none service to keep your pumping station working smoothly.
