C.R.I. Self-Priming Jet pump's casing and ejector unit is designed carefully to give the best possible hydraulic efficiency and suction lift characteristics. Sealing is by means of bellows mechanical seal made of Carbon & Ceramic is fitted over the shaft, which is grounded to close tolerances. Most modern and highly sophisticated machinery and technology are employed in the manufacture of these pumps using quality raw materials, seals and ball bearings to ensure long life. High operating efficiency results in lower power consumption. Dynamically balanced rotor ensures vibration free and noise free operation. Inbuilt thermal overload protector in all single phase pumps to prevent overload.
