S20/2D
Bearings
The stainless steel motor shaft is supported in lubricated-for-life
ball bearings.
Shaft sealing
Between motor and hydraulic section by means of a high quality
sealing unit using a silicon carbide mechanical seal, independent
of direction of rotation and resistant to temperature shock. Seal at
motor side is by oil lubricated lip seal.
Discharge
Piranha 09: 1¼” internal thread Piranha S10 to S30: DN 32 flange
(1¼” threaded adaptor available as accessory)
Shredding system
Spiral bottom plate and stationary cutter ring combined with
a shredding rotor located before the impeller, for optimum
blockage-free running.
Temperature monitoring
TCS (Thermo-Control-System) with thermal sensors in the stator
to switch off the pump in the case of overheating and switch on
automatically after cooling down.
Seal monitoring
DI system consisting of a sensor in the motor and oil chambers
which activates an alarm if there is leakage at the shaft seals.
Not available for Piranha 09
