Blackmer XL1.5-PO 1-1/2″ Sliding Vane Pump Viton/FKM Seals 51-80 PSI Relief

Blackmer XL1.5-PO 1-1/2″ Sliding Vane Pump Viton/FKM Seals 51-80 PSI Relief

Product Description

The Blackmer XL1.5-PO is a heavy-duty 1-1/2 inch positive-displacement sliding vane pump designed for industrial processing, filling, and liquid-transfer applications. The XL Series uses a rugged ductile-iron construction and a replaceable casing liner/end-disc design to provide dependable service and simplify rebuilding and maintenance.

This configuration is supplied with Viton/FKM seals and an internal pressure relief valve with a 51–80 PSI spring range. Blackmer identifies the 51–80 PSI relief-valve spring as the standard spring option for this series.

The XL1.5 uses 1-1/2″ NPT tapped connections and is designed as a motor-speed, base/foot-mounted pump. Its sliding-vane pumping principle provides consistent positive-displacement performance for industrial liquid handling.
