General information
Application
- The submersible pump PZs-145 is a high-performance centrifugal pump designed for transporting contaminated wastewater mainly in food and other industries, as well as municipal wastewater and sludge.
- The pump is suitable for pumping liquids containing solids and soft contaminants (of a certain size)
- The pump can pump aerated liquids.
-
Submersible pump applications
- Wastewater in the food industry
- Wastewater in the chemical industry except for flammable liquids
- Sludges
- Rainwater pumping stations
- Other applications (by agreement with the manufacturer)
General characteristics
The PZs-145 type pump is a submersible pump designed for vertical operation. Together with the motor, the pump is a closed monolithic structure supported on a support ring that also acts as a distance between the inlet port and the ground.
Pump impeller - open, seated on the extended shaft of the motor driving the pump. Outer casing of pump with enlarged space to allow pumping of large particle size impurities mounted with cap nuts to pump casing.
A double mechanical seal is fitted in the pump casing, which is flooded with oil designed to lubricate the seals and prevent the pumped liquid from entering the motor.
The electric motor is designed for total immersion in the pumped liquid. Pump execution in acid-resistant steel 1.4404.
The pump is CE-marked.
