The impeller of an HSC pump is dependent on even water flow entering the eye (or inlet) of the impeller. There are two entry points of water into an impeller of an HSC pump, which is where the term “double suction” is used. If water enters the impeller unevenly, hydraulic imbalance can occur and cause stress to the pump shaft or bearings.

 

The need for smooth, laminar flow in the suction piping of an HSC pump is precisely why the NFPA 20 has strict rules regarding the length of straight piping required on the suction side of an HSC pump (see NFPA 20 2013 4.14.6.3.1, and 4.14.3.1). As a general rule, the larger the volume of water to be pumped, the more important it is to have smooth laminar flow of water into the pump casing.


The orientation of an HSC fire pump must be predetermined when such a pump is manufactured and installed. The pump must be built for either right-hand (clockwise) or left-hand (counter-clockwise) from the vantage point of the driver. For diesel-driven fire pumps, the pumps can only be operated at a clockwise rotation.

 

Failure to pay attention to this can lead to a pump that must be taken apart then reassembled in the correct rotation in the field (if the pump is driven by an electric motor), or piping that must be rearranged in the case of a diesel engine-driven fire pump.

 

Finally, due to the extra bearings, larger impellers, and overall larger size of the horizontal split-case fire pump, the cost is higher when compared to a pump with a cheaper design. The higher initial cost does afford you a pump that will last longer, and will be easier to maintain or service when compared to other pump types.

 

Advantages

 

First-Class international technical standards.

CNP NM FIRE is the first member of NFPA from China pump's manufacturers.and won the UL,FM international fire certification for fire pump products.

 

First-Class testing and inspection equipment.

UL certification represents the world's highest technical standards of fire certification,but also means that certified fire products must withstand the most extreme,harsh test process,the purpose of certification designed to verify whether the product meets the performance,safety and quality requirements,so as to achieve the purpose of property protection.
NM fire obtained fire diesel engine UL1247 and fire pump UL448 witnessed laboratory accreditation,fully proved that the company in terms of hardware and software strength,are to meet the strict requirements of UL certification.
