Draper 61621 Submersible Dirty Water Pump with Float Switch ,Blue

Product Information

This pump has a double vertical float switch system. This is so that you can adjust the water level that the pump both starts and stops. With routine maintenance, sump pump float switches can last up to ten years. How high should I set my sump pump float? Power cut: The float switch and pump are electromechanical devices. The equipment fails to operate accurately to drain the water during power failure. Wide or narrow-angle float switch: Narrow-angle float switches can cause the pump to turn on or off, even with minor changes in water level, like ripples. Turning the pump on and off rapidly can damage and shorten its operating life. For a wide-angle float switch, the water level needs to change by several inches to cause the float switch to either turn on or off.

Submersible pumps can be used for a range of applications. Single stage pumps (one impeller) are used when working with sewage pumping, industrial pumping, drainage, pond filters and effluent pumping. Multiple stage (multiple impellers) they are typically positioned in a borehole, and will generally be used for domestic, business and industrial water abstraction, water wells and oil wells (to create “artificial lift”). They can also be used in seawater uses, firefighting, well drilling, offshore oil drilling rigs, sewage treatment plants and irrigation systems. The delivery head indicates how many metres the submersible pump is able to pump up water through a discharge hose/tube. It is based on a wide discharge hose/tube with as little resistance as possible. The pump capacity (also called flow rate) of a submersible pump determines how many litres per hour the device is able to process in the most optimal situation: this means without resistance and without needing to pump the water upwards. The delivery head and the pump capacity are focal points in choosing the right submersible pump. After all, you do not want to wait forever until a certain space is drained.Ebara BEST ONE MS Automatic operation allows the pump to be used for draining basements, garages, cellars or anywhere that is prone to flooding Tip: Apply a wide margin when you determine which submersible pump is right for you. If in your situation the device needs to pump the water five metres upwards, you should opt for a submersible pump with a delivery head of at least seven metres. Type of water

The Ebara BEST ONE MS is the market leading domestic and light commercial submersible drainage pump in the UK. Ideal for pumping cellars, dewatering ground, pumping floodwater and pumping septic tanks. Standard versions can pump solids with a maximum diameter of 10mm. Vortex impeller versions can pump solids up to 20mm in diameter. Versions are available with and without an integral float switch - 'M' versions are without, 'MS' versions have a magnetic float switch and 'MA' versions have a standard float switch for automatic operation.. Vortex impeller versions have the designation 'VOX'. External interference: The floating element tangles in the basin. Often it gets trapped between the pump and the basin wall and cannot rise or drop to the desired levels. This issue can be resolved easily manually. The Ebara BEST ONE MS is a popular, high quality submersible drainage pump with a magnetic float switch allowing it to operate automatically in sumps as small as 200x220mm. These pumps are fully protected so they can be permanently submerged and are a highly reliable choice for domestic installations. The BEST ONE MS version has the following features:Float switch wears out: The float switch may stop reacting to the rise and fall of water in the sump after many lifting and lowering cycles. Also, the components of the switch can fail mechanically. Replace the float switch in this case. Compact dimensions. Manual-automatic switch. Continuous operation. Low level pumping. Integrated float switch. Moisture sealed cable inlet.
