■ SLURRY PUMP AND VALVE
XPA 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
Based on the outstanding wear resistance of world-famous Xinhai rubber and the molded rubber flow parts, XPA series
of Xinhai wear-resistant rubber lined pump has absolute authority in terms of wear resistance. It has the features of
smooth operation, energy convervation, low noise, large flow, high lift, cost saving, high efficiency, easy maintenance,
and durability;
The maximum concentration of pulp delivery should be no more than 65% (weightometer);
The temperature of pulp delivery is among - 40 ~ + 70 ℃ .
