Kirloskar SP SPM Self-Priming Centrifugal Pump - No Foot Valve Automatic Priming

Kirloskar SP/SPM Self-Priming Centrifugal Pumps

The Kirloskar SP/SPM series are automatic self-priming centrifugal pumps that evacuate air from the suction line and prime themselves without external vacuum assistance or foot valves. Manufactured by Kirloskar Brothers Limited (KBL), the SP is designed for clean water and liquids with mild solids, while the SPM is the non-clog variant with open or semi-open impeller for sewage, sludge, and fibrous material handling. Both models feature an integral priming chamber that retains liquid for automatic re-priming on restart, making them ideal for construction dewatering, sewage transfer, drainage, and mobile pumping applications.

The SP/SPM self-priming pumps eliminate the need for foot valves, suction line check valves, and external vacuum priming systems, significantly simplifying installation — especially for temporary, portable, and emergency pumping setups. The integral priming chamber retains liquid after shutdown, enabling automatic re-priming on restart without manual intervention. The SPM non-clog variant handles sewage, sludge, and solids-laden liquids with its open passage impeller design. Available in both 50 Hz and 60 Hz configurations with gland packing or mechanical seal options, these pumps are engineered for construction site dewatering, sewage transfer, flood emergency, tank emptying, irrigation from open sources, and industrial effluent handling.

Frequently Asked Questions

The SP is a self-priming centrifugal pump designed for clean water and liquids with mild solids. The SPM is the non-clog variant with open or semi-open impeller designed for sewage, sludge, and liquids containing fibrous materials and larger solids. Both feature automatic self-priming without foot valves.
A self-priming pump has an integral priming chamber that retains liquid after the initial fill. On restart, the pump recirculates this retained liquid to create a vacuum in the suction line, evacuating air and drawing liquid from the source. This eliminates the need for foot valves, check valves on the suction line, or external vacuum priming systems.
SP/SPM self-priming pumps are used for construction site dewatering, sewage and wastewater transfer, drainage systems, flood emergency pumping, industrial effluent handling, tank emptying, irrigation from open water sources, mobile pumping units, and applications where suction lift is required without foot valves.
SP/SPM self-priming pumps can achieve suction lifts up to 7-8 metres depending on the model, liquid temperature, and altitude. The self-priming capability eliminates the need for foot valves on the suction line, simplifying installation especially for temporary or mobile pumping setups.
Yes, the SPM variant features a non-clog impeller design specifically engineered to handle sewage, sludge, and liquids containing fibrous materials and suspended solids. The open passage design prevents blockage and ensures continuous operation even with stringy or fibrous debris.
Yes, Target Marketing provides complete support including pump selection assistance, installation guidance, commissioning, spare parts supply, and preventive maintenance services for all Kirloskar SP/SPM self-priming pumps.
