Vertical, centrifugal, single-stage cantilever type pump (impeller located behind bearings), with one-way inlet impeller.
- Pump type Centrifugal
- Installation method Vertical
- Flow 2000 - 36000 m³/h
- Pressure range 20 - 140 m
- Efficiency up to 90%
Pumps of the S-DVN series are designed for pumping domestic, industrial wastewater and other contaminated liquids in the systems of main and auxiliary pipelines, with a limiting pressure of up to 2.5 MPa
- The main pump bearings are rolling bearings lubricated with grease
- The axial force generated in the pump is taken up by the pump bearings and is not transmitted to the electric motor
- The design uses an open impeller with an adjustable gap "S" and additional blades to prevent the penetration of abrasive particles into the seal chamber of the bearing unit
- Corrosion-resistant execution of the flow part
- Operation of bearing units - more than 50,000 hours
- Depending on the pump size, a hard-alloy segment plain bearing can be additionally installed in the impeller area, designed to absorb the residual radial force
- Vibration of the pump in the nominal mode does not exceed 2 mm/s, and within the limits of the operating interval of supply does not exceed 3 mm/s
- Up to three inspection holes with a diameter of at least 180 mm (optionally, the diameter and number can be increased)
