Installing Two Pumps for Tandem Operation
When greater flow rates are needed, two pumps may be installed in the same piping system by means of a
manifold. If installed according to the Figure 17, tandem systems offer backup support so 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 mainte-
nance and troubleshooting (see Figure 17).
