Product catalog summary

Applications:
These pumps are designed for use in refineries and the petrochemical and chemical industries.

1. Robust Design:

High-quality casting with a corrosion allowance of 3 mm.
Seal chambers are suitable for mechanical seals of extended design, including back-to-back API 682 or tandem arrangements.
Axially clamped outer and inner bearing rings.
Minimized axial forces and reduced radial forces through the use of a diffuser.

2. Maximum Operating Reliability:

Shaft and bearings are dimensioned to minimize shaft deflection, ensuring long bearing life.
Bearing insulator extends bearing life and maintains a cleaner oil sump.
Cooling of the bearing bracket is possible under extreme operating conditions.
Mist lubrication is an option.

3. Easy to Service:

Constant-level oiler ensures a consistent oil level and simplifies inspection.
Movable bearings facilitate easy assembly and accommodate thermal expansion of the shaft.
Cooling or heating of shaft seals is possible.
The dry shaft is not in contact with the pumped fluid.
Draining is possible with a flange connection.

4. Flexibility:

Flanges are available in compliance with all standards up to PN 100.

5. Optional Features:

Optional fan cooling for non-drive end bearings.

Technical Data:

Pump sizes: DN 50 to 150.
Flow rate (Q): Up to 450 m³/h.
Head (H): Up to 400 m.
Operating pressure (p): Up to 100 bar.
Operating temperature (t): -80 to +450 °C.
