  • Product Description

Tobee® TWQ-G Submersible Grinder Pumps are designed with a grinder system which grinds solids into small pieces so that they can be LED away through pipes of a relatively small diameter. It is wide used to transport the sewage and filth containing grains or other corrosive medium in sewage treatment, waste water transport, drainage system, chenical engineering ,petroleum, pharmacy, mining, paper making, cement mill, steel works, power plant, coal processing and other public works etc

Design Features:

• TWQ-G adopts the unique single/double-blade impeller structure, which can allow the effictive passing of fiber matters with a diameter being 5 times & 50% of the pump diameter, thus improving the trafficability of filth greatly.
• Mechanical seal adopts the material of new hard corrosion-resistant titanized tungsten.
• TWQ-G boasts a compact and integrated structure,low noise, a noticeable energy-saving effect and being easy for overhaul without building up a pump room because it can be directly submerged to work, thus reducing the project cost greatly.
• The inside of its seal oil chamber is provided with a high-precision anti-jamming sensor for water leakage detection and the thermal elements are buried inside the stator winding in advanced for the automatic for the water pump motor.
• A fully automatic control cabinet is optional in accordance with user needs for the automatic protection of the pump from water leakage, creepage,overload,overtemperature and so on, thus improving the safety and reliability of the product.
• The floating ball switch can control the pump to start and stop automatically in accordance with the required.
• TWQ-G series is provided with an optional double-guide automatic coupling installtion system in accordance with user needs, which facilitates the installation and maintenance greatly, so people needn't pass in and out of the sump.

Tobee® TWQ-G Submersible Grinder Pumps Impeller Design:

Submersible Grinder Pumps Large-channel impellerLarge-channel impeller

Be used for carrying the wastewater with large solid particles.

Large-channel impeller runs in the volute vasing. The shape and size of channel doesn’t bring

the jam, therefore, it is the ideal that the impeller is acted as pump to carry the waste water with

large solid particles.

Submersible Grinder Pumps Vortex impellerVortex impeller

Be suitable for waster water with solid particles.

The water process of vortex impeller that is the impeller triggers the vortex flow in rapid rotating

and makes hydraulic pressure rise.

Submersible Grinder Pumps Multi-vanes impellerMulti-vanes impeller

The impeller is designed into multi-vanes type, it can carry water effectively without blocking.
