Inline pump is a type of centrifugal pump
with a vertically oriented shaft. The inlet and outlet in the pump casing with
same size at the same level, that’s in a line. Therefore, Inline pump can
installed in the pipeline anywhere, that’s why it’s named inline pump (also
named booster pump).
Inline pump with similar performance as end suction pump, but compared to a horizontal end
suction pump, the pump great savings the floor space, and more convenient to
install (do not need to change the piping direction like install a horizontal
end suction pump), because of the unique structure.
There without a universal water pump at
world, different location with different types pump, same as inline pump. For
different operate conditions and request, how to select a suitable pump are
particularly important. Inline pump also with various types for different use.
How to select an inline pump?
Yaness as a pump industry leader and professional
manufacturer at China, manufacture series type’s inline water pump as below.
Due to the variety of inline pumps, we
classify them according to different classification standard.
Pump type– According to different
installation, the inline pump with vertical type and horizontal type.
inline pump (ISG), the motor with extension shaft directly mounted
impeller, to balance the radial and off-load effective when working, thereby
ensure pump stable operation, and low noise. And easy to disassembly, all rotor
components can extract by remove the coupling nut.
According to the request flow and head,
pumps can install in series or in parallel to adjust the flow and head.
And for the horizontal inline pump (ISW), the performances are same with
vertical line pump, but horizontal structure (level suction connection, and
upward discharge connection). The following types pump also with horizontal
type, no longer elaborate.
In addition, Yaness also product vertical inline pump without pump base (SG),
for dangling install at pipeline, like a valve. And detachable inline pump with standard shaft motor, for easy to replace
Drive mode– Normal inline pump adopt
normal motor. For some specials operate condition, we choose low speed motor,
Ex motor and magnetic drive.
low speed inline pump, the structure are same as
ISG inline pump, but with low speed motor (Four holes or six holes). For four
holes, the flow is 1/2 of standard flow rate, and the head is 1/4. For six
holes, the flow is 1/3 of standard flow rate, and the head is 1/9.
With low speed, the pump is more stable,
longevity, and low noise during movement rather than ISG inline pump.
explosion- proof inline pump, adopt Ex motor,
mainly deal with flammable and combustible lquid, or fire-fighting operation.
Liquid type- The material of ISG inline
pump is cast iron, not suitable for corrosive liquid. According to the liquid
corrosives, we should select different material for pump.
For low corrosive liquid, IHG chemical inline pump with stainless
steel 201, 304, 316 are good choosing. For high corrosive liquid, fluoroplastic inline pump are more
suitable, the pump with cast iron casing, inside fluroplastic flowing through
As for hot water, we should choose IRG hot water inline pump, it’s can
transfer liquid up to 240℃. Normal ISG pumps are suitable for liquid less than 80℃.
For oil, YG oil inline pump are design to transfer oil, with bronze impeller
and Ex motor, suitable for diesel, gas oil, kerosene etc.
About sea water, bronze marine inline pumps are widely used at ships. The pump
casing and impeller are bronze and mechanical seal are design for sea water.
For sewage water, GW sewage inline pump adopt a mass flow impeller, and
wear-resisting seal. The pump can convey sewage water with solid particle and
fiber. Also, Yaness product others type sewage pump.
Summary, there have many type inline pumps
with different application. For easy study; we list those applications and
advantages as the follows.
●Transfer clean water
●Convey corrosive liquid
●Deal with flammable and combustible liquid
●Pollution discharge and drain sewage water
●Water supply for high building
●Save floor space
●Easy to dissemble and maintain
●Easy to installation
AS a novel pump, inline pumps widely use at
a different area around the globe. Gradually become the most popular pump.
Yaness with 20 years of experience in manufacturing, and marketing inline pump,
and has been endorsed unanimously by both domestic and international markets.
