Construction and sealing
Pump cross-section, design features and sealing chamber arrangements as given in manual MTEC-03/00.
Design features
Sections 2.1 to 2.3 (p. 7)- Casing (Body)
- Spiral-shaped casing, cast as a single piece and supported on its own feet. Features a suction-side wear ring.
- Impeller
- Radial type, single suction, with pressure-side wear ring. Except models 25-150, 32-125 and 32-125.1.
- Shaft
- Assembled with protective sleeve in the sealing area. Packing or mechanical seal for sealing. For fluids with solids, consult FB.
- General description (p. 1)
- “Back-pull-out” construction: the bearing assembly comes out of the volute without disconnecting or misaligning the piping, which eases assembly, disassembly and maintenance. Mechanically, the pump follows ASME B73.1; the external dimensions broadly follow ISO 2858.
Sealing chamber arrangements
Section 10 (p. 11)ST - Standard
Lubrication by pumped fluid / internal sealing. For clean, non-aggressive fluids. Up to 160 °C.
S1 - External Source
Sealing by external clean liquid. For toxic, aggressive, foul-smelling fluids or vacuum suction. Up to 105 °C.
S2 - External Lubric.
External lubrication and sealing. For fluids with solid particles or fibers in suspension. Up to 105 °C.
S3 - Flushing
Flushing with external clean liquid. For fluids with abrasives or crystallization risk. Up to 105 °C.
S4 - Thermal Oil
Pure graphite and/or graphite with carbon fiber packing. No connections. Above 260 °C.
S - Mechanical Seals
Per application requirements and manufacturer consultation.
(*) External source applications cannot use a cooling chamber. The arrangement temperatures are those in section 10 of the manual; in Table 1, with packing and without a cooling chamber, the range is −50 to 105 °C.
