SPD Series

SPD Series Vacuum Pumps

The SPD Vacuum Pumps allow for the conveying of free-flowing pelletized plastic materials and regrind using vacuum receivers integrated into a central conveying system. SPD pumps are designed for 24 hour, continuous operation and are recommended for most conveying applications. Sterling is able to provide several types of ultra-compact vacuum power units to suit your conveying needs.

The SPD Series uses a high efficiency, positive-displacement vacuum pump and can be utilized to convey pellets and regrind over long distances up to 500 equivalent feet.

SPDB vacuum pumps have the same features as the SPD but include an exclusive non-reversing air valve system to reverse air flow and clean the pump filter.
