Fluid Management DQ series submersible sewage pumps.
Robust and reliable solids handling pumps for municipal,
residential, industrial buildings, hotels, hospitals and many
other sewage and waste water applications.
The FML WQ range is robustly constructed for years of
trouble-free operation reducing your long term operational costs.
FML WQ Submersible Pump Product Features
Bearings:
SKF NTN bearings, robust and durable to extend pump life
Cooling:
Built-in cooling system allows the pump to be partially orfully submersed. A proportion of the pumped liquid is circulated through the cooling barrel to cool the motor. Where external cooling is required, the cooling sleeve may be separated from the pump casing, and individually connected to the cooling system.
Motor:
Class F insulation, maximum working temperature 155 Deg. C. IPX8 protection with seal.
Mechanical seal:
Double mechanical seals to protect motor. Tungsten carbide/tungsten carbide on pump side. Graphite/silicon on motor side.
Oil chamber:
Mechanical seals are oil lubricated to prevent liquid penetration into motor.
Impeller:
Optimised design to handle various liquids with maximum efficiency. Single blade, dual blade and three blade available.
Casing:
Using CAD/CAM design to maximise efficiency and minimise wear.
Shaft:
The shaft has been designed to be as short as possible, reducing deflection and vibration. This extends the life of the mechanical seals, bearings and reduces operational noise.
Monitoring System:
Three heat control switches are embedded in the stator. These are activated should the stator temperature exceed 125 degrees C.
A water leakage probe is mounted inside of the oil chamber. Should the oil water ratio reach a pre-determined ratio a warning signal will be activated, and the pump switched off. [The oil in the chamber should be replaced at regular service intervals].
All motors greater than 30kW are fitted with cable seal leakage detection.
