Hose options
Accessories
1. Discharge Pulsation Dampener
Fitting a pulsation dampener in the discharge
line eliminates up to 90% of discharge
pulsations, protecting the pump, pipeline and
instrumentation and reducing vibration, hammer
and noise.
2. Inlet Pulse Accumulator (IPA)
When installed on the suction side, an IPA
reduces positive and negative spikes when inlet
conditions vary. This results in quieter operation
and maximized hose life.
3. High Level Sensor
When connected to a motor controller, the high
level sensor can trigger a pump shutdown in the
event of a hose element failure.
4. Variable Frequency Drive (VFD)
An integrated frequency inverter, with variable
speed control, for use where pump capacity
must be flexible or the process needs to be set.
