| How does a Pulse Pump work on a Piston Pump? |
| A pulse pump is a high-pressure chemical injection device that is mounted onto a piston pump by a specially ported discharge manifold. The pulse pump injects the chemical downstream of the primary pump, eliminating chemical exposure to the main pump. The pulse pump permits high-pressure chemical injection up to 1000 PSI. This high-pressure injection option is available on the piston pump models 335, 435, 1015 and 2525.
A standard pump can be converted to a pulse pump version [pump model numbers ending in 5]. First exchange the standard discharge manifold with a pulse pump manifold [6400 for 4 FR pumps] 6410 for 10 FR pumps and 6425 for 25 FR pumps]. Second, convert from the standard quiet valves to the flat valves in the 4 FR and 10 FR pumps. The Spring Retainer for the QV assembly is not adequate to house the extra support spring used with the Pulse Pump Manifold. Note: 25 FR comes standard with flat valves.
Once the correct pulse pump manifold is installed, you can select and install the pulse pump [chemical injector]. [select 6300 for 4 FR and 10 FR pumps] [select 6305 for 25 FR pumps]. The valve chamber for the pulse pump is slightly deeper than the other two valve chambers. Special parts are used in this deeper valve chamber, while the standard flat valve parts are used in the other two valve chambers. Pumps with the special manifold port and the Pulse Pump must be ordered seperately.

| How does a Pulse Pump work on a Plunger Pump? |
| A Pulse Pump is a high-pressure chemical injection device that mounts directly into any inlet valve port on the manifold head on several popular plunger pumps. This stainless steel pulse pump permits downstream chemical injection up to 3000 PSI eliminating chemical exposure to the main pump. Once the Pulse Pump is primed, the chemical is drawn into the Pulse Pump by the stroke of the pump or pulse to that valve chamber and injected into the high-pressure line. The amount of chemical injected can be controlled with a metering valve. No pump modification is required. Using special adapters, the 6350 Pulse Pump easily mounts onto 3CP, 5CP, 7CP, 5FR, 7FR and 15FR plunger pump discharge manifolds. |
