The efficiency of machinery used is an important factor for plant operators, as increasing operating costs have become a topic of focus. By using a frequency converter, the motor speed is continuously adjustable to allow the regulation of capacity during the filling and dosing process. The adjustment can be made with the keypad of the frequency converter, via software with a LAN connection, or with an app using the Bluetooth connection of a smartphone or tablet.
Benefits from using a frequency converter
/ Motor speed continuously adjustable
/ Easy switching of direction from right to left
/ Integrated overload protection
/ Highly efficient energy use
/ Pluggable Bluetooth stick
Benefits from using the app
/ Real-time adjustment of speed and power consumption
/ Wireless operation via Bluetooth
/ Fault analysis with fault history
/ Save, load, and send parameterization
/ A 100 % compatibility to PC software
Download the app free of charge in the App Store / Google Play Store, install the connection and operate your unit effortlessly.
How does a flexible impeller pump work?
The flexible impeller turns within an eccentrically formed casing creating a suction via the flexing of the impeller blades, which draws the fluid into the pump casing. The medium itself acts as a lubricant between the blades and the casing, therefore minimizing friction and allowing smooth fluid transfer. In order to avoid possible damages to the pump it is recommended to install dry run protection to each flexible impeller pump by ZUWA.
1. Suction
On the suction side the compressed blades begin to straighten. The chamber space between each blade enlarges and creates a suction pulling the fluid into the pump.
2. Transport
As the impeller turns the fluid is positively displaced from inlet to outlet. Small solids are also able to be transferred freely through the chambers.
3. Pressure
On the pressure side the blades of the impeller begin to flex causing the chambers to shrink, therefore forcing the fluid in a constant flow out of the pump.
