Installing Pumps for Multiple Pump Operation
When greater flow rates are needed, up to four pumps may be installed in the same piping system by means of a
manifold. If installed according to the Figure 20, operations can continue if one pump stops working.
Proper check valves with pressure relief are required to be installed in the discharge
line of each pump to prevent product from being pumped through the pressure relief
system of the adjacent pump when it is not operating.
Ball valves should be installed at the pump end of the discharge line for ease of
maintenance and troubleshooting (see Figure 20).
Figure 20. Multiple Pumps
Siphon Ports
The siphon port for The Red Jacket VSFC STP is in a siphon assembly that fits into one of the two vacuum ports
(see Figure 21). The port end can be swiveled after loosening the hex on top to accommodate the incoming
siphon tube. Torque the siphon assembly to 15-30 ft-lbs (20-41 N•m) after positioning.
The 1/4" NPT plug in the siphon assembly should be removed and the siphon line attached.
Before installing pipe threads, apply an adequate amount of fresh, UL classified for
petroleum, non-setting thread sealant. For AG applications, Loctite 564 is
recommended for all field serviceable pipe threads. Apply sealant in a manner that
prevents it from entering and contaminating hydraulic cavities.
