Submersible chemical pump made of metallic materials
Typ GVSN
Area of application:
Aggressive, also contaminated liquids and
molten materials such as e.g. sulphuric acid at all
concentrations, liquid sulphur, PSA, tar, molten salt
Design features:
- Closed impeller
- Compact double volute casing to
balance out radial loadings
- Shaft column separate from
discharge pipe
- The shaft is supported in
anti-friction bearings above the mounting flange and
corrosion resistant sleeve bearings which come into contact
with the medium. One or more intermediate bearings for
submersion depths greater than 2,100 mm
- Shaft sealing by stuffing box
(normal / gas tight / cooled / heated or mechanical seal
(single / double / gas sealed)
- Fully heated and magnetic coupling
possible
Working temperature limits:
-160°C to +550°C (with magnetic coupling up to 350 °C)
Materials:
0.6025, 1.0619, 1.7357, V 5700, 1.4136 S, 1.4306 S, 1.4408, HA
28 5, R 30 20, RHSX, RHRS, R 70 C1, R 70 B1, titanium
