SECTION 5.5 – GENERAL MAINTENANCE
Flush the Pump with a
Compatible Solvent
1. Flush often enough to extend life
of piston seal and to prevent fluid
from drying in the pump with
possible damage.
2. ALWAYS flush before storing.
a. If you had been pumping a water
based fluid, flush the pump with
BINKS Pump Purj prior to stor-
age. Follow all Pump Purj label
instructions. Residual Pump
Purj will prevent corrosion.
Flushing with Mineral Spirits or
with another compatible solvent
prior to storage is also an option.
b. Leave the Binks Pump Purj in
the pump to protect the pump
parts from corrosion.
3. For maximum protection, be sure to
eliminate all air from the system.
4. Be sure that all solvents used are
chemically compatible with the
wetted parts in the pump and with
the fluids being pumped.
Tighten Threaded Connections
1. Check all hoses before each use
for wear or damage and replace as
necessary. Be sure all threaded
connections are tight.
2. Check and tighten all threaded
connections, including manifold
screws, clamps, plugs, and valve
screws at least every six months.
Check and Service the
Regulator and Filter
1. Follow service instructions supplied
with air control components.
2. To reduce icing due to excessive
water in the air supply, use ethylene
glycol anti-freeze.
Double Sided Seats
Binks Exel pumps have double sided tungsten carbide seats installed at the factory in the tapered edge orientation
(below left). This orientation is optimal for most types of coatings. However, if a highly viscous or filled material is
used, the seats may be flipped over for use in the sharp edge orientation (below right). Be sure to note orientation
when disassembling and reassembling the pump.
CAUTION
Never run this pump dry (without
material) for prolonged periods of
time. Running the pump dry creates
heat and friction, which could damage
some of the internal parts, causing
pump failure. Improper operation of
the pump will void your warranty.
!
CAUTION
Never store de-ionized, distilled,
reverse osmosis, or any pure grade of
water in the pump. These fluids may
cause corrosion.
!
WARNING
To reduce the risk of fluid injection, static
sparking, and splashing, read and follow
Flushing Safety under FIRE OR EXPLOSION
printed earlier in this part sheet.
