NS Non Clog Submersible Pump

Product catalog summary

Submersible Sewage Pumps Type - NS

Pump Casing: The pump features a radially split casing with an integral delivery nozzle. The axial suction and central horizontal delivery nozzle, along with a semi-concentric casing, reduce radial thrust and ensure vibration-free performance. The wide volute passage prevents clogging.

Impeller: Designed to be non-clogging, the impellers allow smooth passage of solids. They are available in single or multi-vane configurations, in semi-open, enclosed, or free flow designs, suitable for various applications.

Shaft: Made of high tensile steel, the shaft is precisely machined and supported by two ball bearings. It is designed to transmit power without vibrations and is common for both pump and motor in a monoblock design.

Mechanical Seals: Two mechanical seals in tandem prevent water or sewage ingress into the motor.

Optional Features: Pumps can include a "Cutter Fan" at the suction for liquid agitation and semi-open impellers with wear plates for cutting fibrous materials.

Bearings: Grease-lubricated and sealed for life, making them maintenance-free.

Direction of Rotation: Clockwise when viewed from the motor top.

Drive: The motor is a dry type submersible, cooled by the liquid handled, and tested for leak-free operation. It has an IP68 protection rating, class F insulation, and operates at 415V ±10% and 50 Hz ±5%.

Cable: The cable is 1.1 kV grade with tinned copper conductors, insulated with a cross-linked elastomeric compound, offering resistance to acidic or alkaline sewage and effluent gases. It is more flexible and lighter than PVC cables.

Control Panel: Includes starter, switch, fuse, and safety features such as single phasing prevention, overload relays, moisture sensing, liquid level controllers, and under voltage/reverse phasing protection.

Flanges: Standard drilling as per IS 6392 table 15.

Constructional Features: Single stage, single suction pumps with overhung non-clogging impeller. Available in stationary and transportable arrangements, with a leak-proof joint using a rubber diaphragm.

Technical Specifications: Detailed dimensions and specifications for various pump models are provided, including nominal size, opening size, suction and delivery size, and other critical measurements.
