Design

Volute casing pump
Horizontal installation
Back pull-out design
Single-stage
Meets the technical requirements to ISO 5199
Dimensions and ratings to EN 22858 / ISO 2858 complemented by pumps of nominal diameters DN 25, DN 200 and above
Hydraulic system components identical with those of standardised chemical pump

Pump casing

Single or double volute, depending on the pump size
Radially split volute casing
Volute casing with integrally cast pump feet
Replaceable casing wear rings

Impeller type

Closed radial impeller with multiply curved vanes
Back vanes or discharge-side sealing gap reduce axial thrust

Shaft seal

Seal-less, with magnetic coupling
Containment shroud as sealing element
Optional: with leakage barrier

Product benefits

High operating reliability:
– No more than 2 static seals are required.
– Containment shroud protected by anti-rub feature and (dis-)assembly aid
– Self-draining facility of containment shroud
– Pump does not need to be drained before drive unit is fitted/removed for servicing

Broad application range ensured by:
– Product-lubricated plain bearings made of silicon carbide
– Temperature-independent mounting of plain bearings
– Temperature maintenance and heating facility for casing, rotor space and bearing bracket lantern

Low-maintenance design:
– Grease-packed rolling element bearings sealed for life (Lh = 25,000 h)
