Technical Specification A1 Monobloc Head Range UPTO 24 METRES Discharge Range UPTO 17.5 IPS Power Rating 0.37 – 3.7 KW (0.5-5 HP) Voltage Range 300-400V (THREE PHASE) 180-240V (SINGLE PHASE) Class of Insulation B/F CLASS Protection IP 44 / IP 55 Material of Construction A1 Monobloc Impeller Cast Iron / Stainless Steel / Bronze Motor Body Cast Iron Delivery Casing Cast Iron Shaft Carbon Steel / Stainless Steel Shaft Sleeve Stainless Steel (Bronze -A1-3lm+) Sealing Gland Packed / Mechanical Seal FEATURES Self Priming : No need of foot valve and priming pump set every time for quicker operations. Non Clog Impeller : Non clog impeller to handle suspended soft solids up to 60 mm in size made it suitable for sewage and dewatering applications. Flatter Efficiency Curve : Minimum variations in efficiency during entire operating range increases the utility of pump set for variable conditions. Designed To Prevent Overloading : Lesser chances of motor burning as the motor does not get overloaded even if the pump is operated at a head lower than recommended, thus ensuring substantial cost savings due to low maintenance and breakdown. Dynamically Balanced Rotating Parts : Minimum vibrations protect components from damages during the operations, thus ensuring consistent performance as concentricity is maintained. Replaceable Wearing Parts : All wearing parts within the pumps are easily accessible and replaceable which facilitates ease of maintenance thereby extending the life of the pump. Easy Maintainable Designs : Easy maintainable design and better interchangeability of components so that pump can be serviced even at remote locations by semi-skilled technicians.
