The HCP AFG range of submersible pumps are designed for site use, mainly for contractors and installers. They are extremely robust and a very useful tool to have on site for any slurry dewatering applications. This series is equipped with a ductile iron agitator to stir slurries and allow easy passage through the pump without clogging. There are various models within this range with solids handling capability up to 54mm. The largest model within this range is capable of achieving flow rates up to 150m³/hr and heads up to 21m.

These slurry submersible pumps are installed with an abrasion resistant impeller, chrome steel wear ring (Models AF-610/615) and silicon carbide double mechanical seals for abrasion resistance

Common applications for the AFG sump pump include; dewatering involving sand and gravel, coal plants, silt removal, civil engineering, storm water sewers, dewatering of newly dug tunnels or ground works, general dewatering of areas containing solids and applications requiring agitation and removal of solids from sump floors.

FAQS

Can this pump run dry?

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.

What do the terms manual and automatic mean?

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.

How do I know what size pump is correct for my application?

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.

Can the motor really be submerged in water?

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.

What size solids can this pump handle?

Please be aware that the figures displayed relate to the largest pump from this range of products, not specific models. For details on solids passage for specific models, please refer to datasheets or contact a member of our sales team.
