Self-Priming Monoblock Pump — SMM Series
Self-priming monoblock centrifugal pump with non-clog impeller — up to 75 m³/hr capacity, 35 m head, 70 °C, 2900 RPM, in CI, SS 304/316/316L, Alloy 20, and Bronze.

The SMM Series is a range of self-priming monoblock centrifugal pumps designed for handling clean and contaminated liquids across industrial, commercial, and marine applications. With a maximum capacity of 75 m³/hr, head up to 35 m, and temperature rating up to 70 °C, the SMM Series covers a wide range of dewatering, chemical handling, and water transfer duties.
The compact monoblock construction eliminates the need for separate motor coupling and alignment, reducing installation footprint and maintenance complexity. A non-clog impeller design handles liquids with suspended solids without blockage, while the flatter efficiency curve ensures consistent performance across the operating range.
All models are fitted with mechanical seals as standard for zero-leakage operation and feature dynamically balanced rotating parts for low vibration and extended service life. The pumps are designed to prevent overloading and come with replaceable wearing parts for easy, cost-effective maintenance.
Available in Cast Iron, SS 304, SS 316, SS 316L, Alloy 20, and Bronze, the SMM Series offers 11 model variants from 0.37 kW to 5.5 kW, all operating at 2900 RPM. Single phase and three phase motor options are available with 240/415 V rated voltage, making the SMM Series suitable for chemical handling, flood water pumping, marine applications, basement dewatering, and package STPs and ETPs.
