Vented Cover (Pressure Relief)
The vented cover option is an internal pressure and flow control which works independent of
flow (rotational direction). The complete assembly can be seen in Figure 63. The relief
pressure is set with the adjustment screw and may require in-line pressure gauges for
calibration. The vented cover is designed for COP (Clean-Out-of-Place) practices.
Jacketed Cover
The jacketed cover option (Figure 64) allows for heating or cooling fluid to be circulated
through to match the demands of certain products. This fluid (media) can preheat or cool the
fluid end and sustain the product temperature during operation and short shut downs. The
jacketed cover is not a heat exchanger and is not designed to primarily control the product
temperature. This option requires longer gear case mounting studs. Please contact Ampco
Pumps for replacement information. The pressure limit for the jacketed cover is 60 psi.
