FEATURES

Operating Parameters:

• Flows to 570 m3/h (2500 US gpm)
• Heads to 100 m (330 ft)
• Pressures to 25 bar (365 psi)
• Temperatures from -80°C (-110°F) to 350°C (660°F)

Features and Benefits:

• Close Coupling eliminates influence of the baseplate and foundation on alignment.
• Radiating Surfaces dissipate heat and extend bearing and mechanical seal life.
• External Impeller Adjustment Mechanism can be carried out without taking measurements (micrometer on coupling).
• Heavy-Duty Casing with integral foot and multiribbed discharge flange offers superior resistance to pipe loads.
• Reverse Vane Impeller is the only impeller design that offers repeatable pump performance throughout the life of the pump.
• Open impellers available.
• SealSentry Seal Chamber extends seal life and provides advanced self-flushing capability.
• Back Pull-out Design allows removal of rotating element without removing the casing or the piping.
• Benefits of the Durco Mark 3 ISO Close Coupled Pump
• Permits use of readily available standard electric motors
• Provides a thermal barrier between the pump and motor
• Reduces installation cost by eliminating pump to motor alignment
• Serves as an additional deflector between the mechanical seal and motor

Muff Coupling:

• The muff coupling is investment cast in two halves (WCB steel).
• Notches at 30° increments around the circumference of the coupling assist in setting the impeller face clearance.

33 Sizes Available:
