North Ridge C Series Sewage Submersible pump

XC Series Sewage Submersible pump

The XC series sewage submersible pump is suitable for many applications in the industrial and domestic markets involving the transfer of wastewater, sewage and many other fluids that contain suspended solids or fibrous content. Common applications include wastewater, dewatering, building systems, mining and energy plants.

The vertical submersible pump design has many benefits:

There are five impeller types to suit most applications, these include; closed, semi open, vortex and cutter.

Capable of high flow rates up to 1600m°/hr. Larger models have a solids passage capability up to 76mm

Single mechanical seals are installed as standard, however double mechanical seals are installed in larger pumps from the range.

The bearings in this submersible pump are greased for life.

Motor cooling jackets are available for higher temperature water up to 40°C.

All XC series submersible pumps are installed with a motor protection and control relay as standard, this ensures reliable operation of the pump. Feedback is also sent to the operator automatically; this means that it is not necessary to remove the submersible pump from the sump for inspection. The control relay protects the submersible pump in several ways; these include stopping the pump in the event of an overload, seal failure, phase failure or overheating. It can also installed in conjunction with float switches to advise the operator during high fluid levels and also enables resetting of the pump in this event.

FAQS

No, definitely not! submersible pumps will incur damage even after short periods of dry running. The mechanical seal requires lubrication and cooling while the pump is operating. Without the presence of fluid, the mechanical seal will overheat and crack, and this may cause the pump to leak and fluid to enter the motor. There is also the possibility that the motor will burn out as this requires cooling by the fluid during operation. Our advice is to ensure that the pump and motor are always submerged during operation. There are two main ways to ensure the pump only operates in the event of submersion. Firstly, only the operator turns the pump on and off manually when they have a clear view of the sump. Secondly, fit the pump with a float switch that will automatically turn the pump off once the fluid has dropped to a specific level in the chamber. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.

Manual and automatic are the two main ways to describe how a submersible pump will operate. Manual means that the operator manually turns the pump on and off when required, turning the pump off and avoiding any possible damage from dry running is solely the liability of the operator. Automatic means that the pump will turn on and off automatically via a float switch or float switches. A float switch is connected to the motor that detects the fluid level in the sump, the pump is turned on when the level is high enough, and the pump is turned off when the fluid drops to an acceptable level.

A clear picture of the pump system is required to make an accurate selection. The main pieces of information required include; a description of the application, bore of pipework, the fluid, flow rate and pressure/head. With these pieces of information, a pump can be sized correctly to ensure it delivers the required flow rate and pressure and that is also operates at its best efficiency point to lower lifetime costs. Knowing if the pump is running intermittently or continuously also allows the correct motor speed to be selected. For instance, a pump running continuously 24/7 will require a 4 pole motor rather than a 2 pole motor. Running the motor slower and oversizing the pump will reduce wear of the motor and the pump, therefore lowering maintenance costs during their lifetime.

Yes, absolutely! In fact, submersible pump motors need to be submerged in fluid during operation for cooling and to avoid overheating. These motors have an IP rating of 68. IP stands for Ingress Protection, this is a measurement of a component's resistance to dust and fluid entering.
