Horizontal chemical process pump

Horizontal chemical process pump
HZ (closed impeller type) chemical process pump is a single stage, single
suction, cantilever type centrifugal pump which absorbs the advanced
technologies from overseas, and is designed based on the advantages of F1, IH,
CZ, ZBG chemical process pumps. HZ chemical process pump owns the features of
better operation performance, anti-cavitation, long life of mechanical seals
and bearings, reliable operation, updated structure and easy maintenance.

ZGPV Chemical Process Pump Features
The impeller is a closed impeller, which uses rear blades and wear rings to
balance axial forces.
The impeller and shaft are connected by a key and locked by a special
impeller nut. Eliminates the possibility of impeller nuts becoming loose during
operation, shutting down, and backflow.
Back-pull design, the rotating part can be removed from the housing without
removing the pipe.
The sealed cavity is designed with a tapered space to install the mechanical
seal into a spacious room. At the same time, the impeller rear blade, the inner
surface and the guide blade work together to form a self-flushing flow sealed
cavity without any external flushing fluid. Self-flushing flow can quickly
eliminate the heat on the friction pair; self-flushing flow can avoid the
accumulation of particles (<5%) between the moving ring and the static ring,
thereby extending the service life of the mechanical seal.

chemical process pump Structure
Single-stage single-suction horizontal centrifugal pump structure, the pump
cover is fixedly clamped in the middle
by the connection between the pump body and the bearing housing, and the pump
cover is positioned with the bearing
port and the bearing housing.
The pump body adopts axial suction, radial discharge, foot support type, and
can be directly fixed on the base. The tail of the bearing housing is supported
on the base by the suspension bracket.
The impeller and the shaft are connected by a key, and a special impeller nut
locking method is adopted to prevent the impeller nut from loosening when the
medium is poured during operation or stopping the pump.
The flushing and cooling interfaces of the pump body, pump cover, bearing
housing and sealing end cover are all made of taper pipe thread, which
increases the reliability of the pipeline seal. The bearing is made of rolling
bearing, oil lubrication, and the oil pool volume is increased.
The structure of the pump is designed as a rear door. When the inlet and
outlet of the pump are not moved during the inspection (ie, the pump body does
not move), the impeller, shaft, shaft seal and bearing components can be
removed.
The large conical cavity of the shaft seal box makes the mechanical seal in a
spacious cavity, and also cooperates with the back vane, the guide vane of the
inner wall of the cavity, and forms a self-flushing flow field in the shaft
seal box, thereby eliminating the need The external flushing fluid is used to
achieve self-flushing; the heat generated on the frictional secondary surface
is quickly taken away, avoiding the accumulation of solid particles (<5%) in
the medium on the contact surface of the rotating ring and the stationary ring,
reducing wear and prolonging the machine. Sealed life
