than these limits, consider using an adaptor on the pump exhaust and a larger
diameter pipeline.
▪ For pumps running on dusty processes, we recommend that the exhaust line is
cleaned regularly as part of routine maintenance. Accumulation of dust in the
exhaust line can reduce conductance and therefore increase exhaust pressure
which may damage the pump. The frequency of exhaust line cleaning depends on
the process. On very dusty applications, use a low-impedance inlet filter to reduce
maintenance requirements.
1. Referring to Figure: Connecting the pump
blanking plate from the inlet of the dry pumping system. Take care not to drop
screws, tools and so forth into the pump inlet. Retain the nuts, bolts, washers and
blanking plate for future use. Retain the temporary cover for future use on
non‑contaminated pumps only. The inlet O‑ring is supplied with the pump, it is
fitted underneath the inlet flange cover.
2. Use the O-ring supplied and suitable nuts, bolts and washers (not supplied) to
connect the inlet flange

designed for use with a trapped O-ring or centring ring. Use our half claw clamps
when connecting an ISO style foreline flange to the dry pumping system inlet.
Refer to Figure: Connecting the pump
3. Use the trapped O-ring and clamp supplied to connect the exhaust outlet
