Use manifolding tighten or under-tighten the drive. A general rule that is no smaller than the pump inlet. Tuthill for correct V-belt tension is to tighten the drive just recommends arranging the inlet manifolding to enough to prevent slippage when operating at full prevent oil migration back into the system. - Page 14 Tuthill Vacuum & Blower manifold is very close to the pressure obtained with Systems. Other types of connectors may be too the pump inlet blanked off.
