Hao
Star ZB series rotary lobe pump is elaborately designed and
made on the base of brining in and absorbing foreign advanced
techniques, compared with foreign like pumps, it has higher
precision, lower cost as well as fresher appearance, it fills
up domestic blank so that it has already been widely used in
various fields.
1、Main differences compared with other pumps:
a)This pump belongs to cubage type pump, can precisely
control transportation flux and also can be made to variable
capacity pump conveniently. While the output flux of centrifugal
pump can not be controlled, it will be reduced along with the
resistance increase; this pump has strong self-suction ability,
while centrifugal pump has to be filled with liquid before rotating.
b)This pump has very low rotate speed, generally between 200rmp
and 600rmp, the transported materials are sent placidly and
their components will not be affected. While centrifugal pump
has high rotate speed, the transported materials receive fierce
impact and centrifugal force so that it is easy to result different
components when transporting mixed materials, and the quality
of finished product is reduced accordingly. However, this pump
is the best solution of this problem, so it is especially suitable
for transporting mixed materials and those containing solid
granules even more.
c)This pump can transport materials with rather high viscidity,
so it is called rotary lobe pump as well. While centrifugal
pump does not have this character.
This pump can conveniently made to the breeds with high output
pressure, for example, 15kgf/cm2， so it is suitable for long-distance
and high-resistance ration transportation.
2、Compared with screw pump (dense slurry pump):
Both of them belong to cubage type
pump, so they have like performances?can placidly transport
high-viscidity material, with high transportation pressure.
But screw pump has a biggest shortcoming, which makes it inapplicable
for the occasions with sanitary requirements? non-streamline
curved surface as well as numerous faults in the cavity, which
also makes itimpossible to be sanitary type pump, at the same
time, the damage of PTFE or rubber on the cavity wall may pollute
transported materials even more. While the rotor of this pump
has streamline structure and there is rarely any dead point
or non-metal part in rotor room, so in food and beverage, medicine
and other callings that have high sanitary requirements, universal
transportation pump is more applicable, besides, automatization
degree of present production lines is higher and higher, and
more and more of them adopt on-the-spot cleaning (CIP), thus,
the importance of Hao Star rotary lobe pump is fully displayed.
