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 a flexible impeller pump works
The impeller turns inside the eccentrically formed casing creating a suction by 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 casing. In order to avoid possible damages to the pump it is recommended to install a dry run protection to each flexible impeller pump by ZUWA.
On the suction side the blades begin to straighten. The chamber space between each blades enlarges and creates a vacuum pulling the fluid into the pump.
With the turning of the impeller the fluid is positively displaced from the inlet to the outlet. Small particles are also able to be pumped freely through the chambers.
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.
A multi-purpose pump designed for transferring clean or contaminated liquids. Not suitable for handling abrasive or corrosive fluids.
This pump is particularly suitable for all fluids containing abrasives. It is an economic alternative to the NIROSTAR series for transferring abrasive or slightly corrosive fluids.
A high quality stainless steel pump with numerous applications in industrial plants and production facilities, the appropriate choice for transferring corrosive fluids.
The synthetic impeller pump for a wide variety of applications in the chemical sector. Perfect for fluids with various viscosities, aggressive acids, bases, and solvents.
