APPLICATIONS
I N D U S T R I A L : Circulating and transferring corrosive liquids.
Returning spilled liquids to process, transferring foaming
solutions with entrained air, such as soaps and detergents.
Sampling and pilot plant installations. Handles pure solutions,
acids, alkalies, photo chemicals, dyes, detergents, waxes,
gels, solutions with suspended solids and emulsions.
M E TA L P L AT I N G : Filtration of plating solutions. Filling and
emptying vats. Adding chemicals for pH balance.
P H A R M A C E U T I C A L : Processing lab solutions, medicines,
lotions and preparations. Filtering pharmaceutical solutions.
A G R I C U LT U R A L : Transferring liquid fertilizers, herbicides
and pesticides.
OPERATING INSTRUCTIONS
1.
INSTALLATION – Pump may be mounted in any
position. The rotation of the pump shaft determines
the location of the pump’s intake and discharge
ports. (Refer to dimensional drawing.) Pump is
normally assembled at factory for clockwise rotation
(looking at end cover). If counter clockwise rotation
is desired, follow steps 1 and 2 of disassembly and
step 9 of assembly instructions to change direction
of impeller blade deflection under cam.
2.
DRIVE – Belt or direct with flexible coupling.
Belt Drive: Over tight belt load will reduce pump
b e a r i n g life.
Direct Drive: Clearance should be left between drive
shaft and pump shaft when installing coupling.
Always mount and align pump and drive shaft before
t i g h t e n i n g the coupling set screw. If pulley or
coupling must be pressed on shaft, remove end
cover and impeller to support shaft from impeller end
during press operation. Do not hammer pulley or
coupling on shaft; this may damage bearing or seal.
