QDFU heavy duty drainage pump
A submersible pump characterised by high resistance to damage and high efficiency. Its design allows it to be installed in places that are difficult to access. The range includes the compact QFDU Professional pump for tight spaces and the QDFU Premium pump for special tasks.
The design of the QDFU Professional pump allows for continuous operation even when the pump is not fully submerged. An additional advantage of the pump is that the motor is also cooled at low flow rates. The pump is ideal for the toughest working conditions, e.g. for dewatering trenches, mines, sewage treatment plants and for rainwater, river and process water. The pump is designed for cold fresh water with sand, mud, sludge, sediment and organic waste.
Manufacturing materials of the QDFU Professional pump
Motor housing/pump body: aluminium alloy,
Impeller: steel/nitrile rubber,
Suction screen: steel,
Mechanical seal: silicon carbide/graphite/ceramic
QDFU Premium pumps belong to a line of pumps for very difficult conditions, made of the best materials with maximum precision. They are designed for cold and fresh drainage, river, process and rainwater containing grinding solids (organic and mineral, e.g. sand, silt, concretite). QDFU Premium pumps are dedicated to work in mines, quarries, drainage ditches and sewage treatment plants. QDFU Premium pumps are specialised equipment for demanding tasks.
QDFU Premium pumps have a special mixer, installed on an extension of the shaft. This intensively agitates the liquid before it enters the impeller chamber, so that sediment and heavy solids, either in the liquid or deposited on the bottom, are pumped out with ease.
Manufacturing materials of the QDFU Premium pump
Motor housing/pump body: cast iron,
Impeller/mixing system: chrome steel alloy,
Base: steel,
Double mechanical seal: silicon carbide
