CASING  
Top centreline discharge self-venting casing design fully confined casing gasket – casing foot support for handling misalignment, distortion from pipe loads and suitable for back pull-out construction.

BACK PLATE 
The back plate is designed for gland packing and mechanical seal installation. The large bore provided in case of mechanical seal arrangement enhances the mechanical seal life. The flow path in series ‘MBM’ pumps is between the rear of the impeller and face of the back plate. The abrasive and erosive wear takes place on the face of the back plate and not on the expensive casing. This feature reduces the replacement costs.

SHAFT  
A single piece shaft is designed for minimum deflection. All critical surfaces are ground for precision fitment of bearings. coupling hubs, etc. Shaft threads are machined with close tolerances for effective impeller fitment. PTFE impeller gasket provides maximum protection to impeller and shaft threads.

IMPELLER  
The unique impeller design offers special advantages not available on conventional impellers:

• Impeller clearances of rotor assembly can be adjusted on the maintenance shop bench itself. This reduces down time of the equipment.
• Efficient pump operation even in marginal NPSH conditions is possible which helps to reduce cavitation problems.
• Helps to maintain low seal chamber pressure, aids efficient shaft sealing and improved seal life.
• The impeller vanes located on the back plate side greatly reduce the thrust loads on the bearings and provide enhanced bearing life.

SELF-PRIMING PUMP 
The casing of the self-priming pump has a built-in priming chamber. The rotor assembly of the standard series ‘MBM’ pump can be used for this pump. There is on need of foot valve or frequent priming of the pump.
