PumpMeter:

Intelligent pressure transmitter for pumps, with on-site display of measured values and operating data
For recording the load profile of the pump
Supplied completely assembled and parameterised for the individual pump

Shaft seal

Single mechanical seals and double mechanical seals to EN 12756 haft equipped with replaceable shaft sleeve in the shaft seal area

Impeller type

Closed radial impeller with multiply curved vanes

Product benefits

Improved efficiency and NPSHreq by experimentally verified hydraulic design of impellers (vanes)
Operating costs reduced by trimming the nominal impeller diameter to match the specified duty point
Little wear, low vibration levels and excellent smooth running characteristics thanks to good suction performance and virtually cavitation-free operation across a wide operating range
Casing sealed reliably – even in varying operating conditions – by confined casing gasket
Optimum match of pump to fluid handled by a large choice of materials for many applications as standard
Extended selection chart with additional pump sizes for small flow rates
Easy to dismantle using forcing crews at the interface of casing cover and drive lantern
