Overview for Grundfos 91122110

The Grundfos TP50-40/4 is a direct coupled, single-stage, in-line centrifugal pump. The TP 50-40/4 is a top-pull-out design, meaning the pump head (which includes the motor, motor stool and impeller) can be detached without interfering with the pump housing's pipework. This simplifies the routine service work needed to maintain the performance of these pumps, enabling a single person to service even the largest pumps. The Grundfos TP series pumps are specifically designed for the circulation of liquids in heating and air-conditioning systems. Typical applications for this cast iron pump include: district heating/cooling, industrial cooling/processes, boiler/hydronic heating, chilled water, air conditioning systems, cooling towers, radiant floor heating, solar and snow melt systems.
  • Advanced fan design
  • Results in dramatically reduced noise levels
  • All-in-one-solution
  • The coupling and shaft are friction-welded together in order to create a completely stable mechanical unit, drastically reducing the vibration levels and prolongs the lifetime of the shaft seals and bearings
  • Mechanically and hydraulically balanced impeller
  • Further minimizes vibration levels and axial forces while maximizing motor bearing and shaft seal lifetime
  • Anti-corrosion surface
  • Cataphoresis surface treatment consisting of Powercon cathodic electrocoating and zinc phosphate coating results in maximal protection against corrosion and a longer lasting inside surface that keeps efficiency high
  • Renewable neck rings
  • Makes it easy to upgrade your pump when necessary
  • Unique design of shaft seal chamber
  • Eliminates the need for external piping and ensures optimal water circulation, prolonging the lifetime of the shaft seal
  • Grundfos Blueflux IE3
  • Only motors with the official IE3 logo are certified maximum efficiency motors
  • Compact perfection
  • A large shaft diameter and a short distance from the impeller to the motor maximizes stability and results in lower maintenance costs
  • Product Note
    Cast iron cannot be used in domestic hot water or potable water applications.
