Low-maintenance pumps from Netzsch
Walsall-based Netzsch Pumps Ltd offer a range of feed pumps for conveying highly viscous, dry and non-flowing products at rates of up to 190m3/h with differential pressures from zero to 24 bar.
The SF range incorporates NEMO pumps that are said to pump and dose more efficiently, deliver more gently, operate more effectively and are easier to service than other more expensive conveying systems.
By force-filling the open rotor/stator chambers continuously, the large patented feed screw is able to pump products that are not capable of flowing and prevents product from lining the inside of the pump body. This increases capacity by up to 50% more than the standard feed screw design.
With the installation of a bridge breaker or mixing paddle, even filter cakes from chamber filter presses can be easily pumped through the SF model.
Friction losses in the pump’s discharge pipes can be reduced by spraying lubricant on to the inner walls using a small dosing pump and ring doser. An additional flange can also be added to the body of the SF pump body, through which thinner sludge can be added to re-liquefy the sludge cake. A block-construction version
is also available for applications where space is at a premium.
