OPERATION INSTRUCTION
SANDPUMPER II
GENERAL OPERATION & SERVICE INSTRUCTIONS - REPAIR:
1.
The SandPumper II diaphragms are operated internally on a
double rod cylinder shaft. A stroke directional limit switch is
mounted between diaphragms and sends a signal to the
solenoid-operated manifold to indicate the end of stroke and the
beginning of a reverse stroke.
2.
The SandPumper II is equipped with two, single ply, neoprene
diaphragms (20 inches in diameter). It is recommended that the
diaphragms be replaced yearly.
3.
The check balls are made of solid neoprene and are 2-1/4 inches
in diameter. It is recommended that the check balls be replaced
every two years.
SUCTION STRAINER:
1.
The SandPumper II material pump system comes with a large one-
gallon basket strainer. The strainer basket has 1/8” hole mesh.
CHECK BALLS:
1.
For most efficient pumping performance, it is recommended
check balls and ball seats are in good working order to ensure
proper seating. Need for inspection or service of check balls is
usually indicated by poor priming, unstable cycling, reduced
performance, or pump cycles but will not pump. Inspection and
service of check balls require the removal of six bolts which
provides access to all four balls, both suction, and discharge.
