Self-priming Jet Pumps


C.R.I’s Self-Priming Jet Pump’s casing and ejector unit are designed carefully to give the best hydraulic efficiency and suction lift characteristics. Mechanical seals are made of carbon & ceramic which is precisely grounded to close tolerances. Most modern and highly sophisticated machinery and technology are employed in manufacturing these pumps using quality raw materials and dynamically balanced impellers, rotors & shafts ensure longer life and noise free operation.
