The Lubi SMSJ-103 1HP 3 Phase SS Monoblock Pump is a compact self-priming centrifugal pump designed for reliable water transfer and pressure boosting applications. It belongs to the Lubi SMSJ self-priming pump series and is suitable for clean liquids without abrasive particles.
The 1 HP pump configuration is based on the SMSJ 101 performance specification, with a 0.75 kW motor rating and 32 × 25 mm suction × delivery pipe size. The documented SMSJ series operates at 2900 RPM, 50 Hz, with a maximum flow rate of up to 90 L/min (5.4 m³/h) and dynamic head up to 40 metres.
For three-phase applications, the catalogue identifies three-phase availability as a special construction available on request.
The pump is constructed with AISI 304 stainless steel for the pump casing and bracket, while the catalogue specifies AISI 304/Noryl for the impeller, AISI 304 for the shaft, and NBR/Ceramic/Carbon for the mechanical seal arrangement.
With continuous-duty operation, liquid temperature capability up to 90°C, ambient temperature up to 50°C, and total suction lift up to 7.5 metres, the SMSJ series can be used across domestic, agricultural, RO and industrial water-handling applications.
