Single-suction pump, also known as end-suction pump, has the advantages of stable operation, simple structure, simple repair and maintenance, convenient installation and small footprint. The single-suction pump has low cost, reasonable price and wide application. The flow rate of the single-suction pump is smaller and the flow rate is equal. The volume of the single-suction pump is smaller, but the axial force is large and the bearing load is large.

Using electric fire pumps safely and efficiently is of utmost importance to ensure effective fire protection. Here are some crucial precautions for the use of electric fire pumps

The pump body –the pump body is in the form of high-efficiency volute. The flange connection size is in accordance with UL448, FM1319, ANSI/ASME B16.1, ANSI/ASME B16.42, GB/T 17241.6(cast iron) and GB/T 9113.1(stee) PN1.6MPa, and can be used with the following standard flanges.: BS 4504:1989, ISO 7005.1:1992, DIN 2533:1976, ISO 7005.2:1988.
The rear open cover design–Can replace the rotor components without dismanting the pipeline.
Replaceable seal ring–The wear of the impeller ring can be achieved only by replacing the sealing ring, so as to restore the best operating condition of the pump and achieve low-cost operation.
Enhanced pump shaft design—The impeller and the pump shaft are designed with a conical surface to improve the matching precision and bonding strength, which is beneficial for effective locking and convenient maintenance during operation.
· Cantilever ratio is small–The cantilever ratio of the rotor ranges from 0.75 to 1.0, with good rigidity and small deflection. Its rigidity is much better than that of the same type of single-stage centrifugal pump (the cantilever ratio of IS pump is between 0.97 and 1.48).
Hydraulic balance design–Further Improve the Stability of Pump Operation, hydraulic balance design and combination of impeller dynamic and static balance.
Single-end mechanical seal design –suitable for occasions where leakage is not allowed.
Packing gland design–meets UL/FM standard design and is interchangeable with mechanical seal.
Reliable bearing structure design–Heavy-duty largesize bearings improve reliability during high-speed and heavy-duty operation.
Imported brand Sealed bearings without grease are selected as the standard configuration, bearing inner seal with high quality greaseto meet the requirements of maintenance-free and environmental protection during the life of bearings. Oil bath lubrication or grease lubrication bearings are suitable for continuous 24-hour operation and medium temperature greater than 80 C. If grease lubricated bearings or oil lubricated bearings are selected, should inform us when ordering so as to provide more suitable products.· High degree of generalization of parts–The whole series only need 4 suspensions,4 pump shafts and 10 pump covers, which effectively improves the interchangeability of parts.
Rotation direction of the pump–from the driving end, it rotates clockwise.
