  • Drive and discharge branch always above liquid level.
  • Medium lubricated friction bearings in pump body and shaft section (number depends on installation length).
  • Suitable for variable speed control.
  • Maintenance-friendly design.
  • Suction bells, suction strainers, or foot valves available.
  • Can design available for pumping hot or condensate media.
  • Inducer design available for low NPSH applications.

Impellers and Casing

• Impellers (Sizes 84-254): Closed radial type, designed for casing wear ring on both sides. Axial thrust minimized by balance holes.
• Impellers (Size MP 300.1 and MP 300.2): Thrust balanced by a balancing drum.
• Diffusor and Casing Design:
  • Sizes 84-104 P: One-piece design.
  • Sizes 124 PA-254 P and MP 300.1, 300.2: Two-piece design for diffusor and stage casing.

Shaft Seal Options

• Seal chamber dimensions comply with ISO 3096. Mechanical seals complying with this standard and EN 12756, version "k" can be used.
• Internal flush system ensures optimum lubrication and cooling of seal faces.
• Mechanical Seals:
  • Single mechanical seal, Design U (unbalanced).
  • Single mechanical seal, Design B (balanced).
  • Cartridge mechanical seals: Single (also with Quench), Double (with connection for external flush).
• Gland Packing: Available, but limited to max. 25 bar operation pressure.

Multioutlet Design

• Available for horizontal (PM, PMA) and vertical (PVAM) executions.
• Can be fitted with a random number of discharge branches, often used in fire fighting applications to serve different pressure zones.
