General Information

These models are one of the BB type pumps of the API610 and designed & manufactured to operate at high capacity and medium pressure and temperatures up to 200°C. The axis in BB1 pumps is horizontal, and their impeller is placed between the bearings. Their casings are axially split, and the impeller of these pumps operate as a single or double suction, and can be one or two stages.

The design of these pumps is vertically slip case (two pieces) with their suction and discharge flanges placed in the lower half of the pump. This design allows access to the rotor for inspection and repair without disturbing the piping and driver systems.

The double-suction impeller of these pumps creates a hydraulic balancer. All impellers are dynamically balanced to make the function of the pump without additional vibration, and also the bearings are cooled in accordance with requirements of API610 standard with lubricating oil and with blowing air or passing water through the bearing converter. These capabilities and production under standard conditions have led to the three years of pump operation without major overhaul and reduced pump repair & maintenance costs.

Application

Hydrocarbon and chemical processes, water projects, water pumping and discharge stations, industrial water supply systems, fire-fighting systems, ships and marine industries.
