SLURRY PUMP AND VALVE
XPA2 High-head Wear-resistant Rubber Slurry Pump
Principle
Driven by motor, the pump body and inlet line are filled with liquid before
starting the pump. With high-speed rotation, the impeller drives the liquid
between the vanes rotate together. Due to the effect of centrifugal force,
the liquid is thrown to the outer edge of impeller from the impeller center
with kinetic energy increased. After the liquid entering the pump shell, as
the flow channel in the volute type pump shell is gradually enlarged, the
liquid velocity is decreased gradually, which makes part of the kinetic en-
ergy transform into static energy, therefore the liquid with high pressure is
discharged along the outlet. At the same time, the impeller center forms a
certain vacuum for that the liquid is thrown out. The pressure on liquid level
is higher than that of impeller center, so the liquid in suction pipe will flow into the pump under the action of pressure
difference. With the constant rotation of impeller, the liquid is sucked and extruded continuously.
Features
Lined with Xinhai wear-resistant rubber, and with standard configuration of molded rubber flow parts, XPA2 series
double-stage wear-resistant rubber pump is a kind of rubber slurry pump with special performance.
Advanced and fresh design of hydraulic power and structure, high efficiency, abrasion resistance, and stable and reli-
able operation;Mass flow and high head;Simple and reliable shaft seal with no leakage;Used in filter-press industry
without frequency control of motor speed, and with high transportation concentration.
Application
It is used for pulp liquid in mineral processing and chemical plant, especially suitable for feeding pressure and tailings
pumps that are specially used for filter press,Breaking the limitation of the working condition that is the rubber pump
cannot be used inthe lift of exceeding 60 meters, and enlarge the application fields of rubber pump.
