Item Overview for Blackmer SGLWD3A
The Blackmer SGLWD3A is a double-ended, base-mounted sliding vane pump built in ductile iron construction for industrial process transfer. Containment comes from PTFE packing backed by PTFE elastomers, a combination chosen for punishing liquids. Weld flanges speed connection during commissioning and later service. Overpressure protection arrives built in, with an internal relief valve shielding the casing and downstream piping. Supplied as a bare unit, it drops into an existing drive arrangement or a purpose-built skid. It also brings a cavitation suppression liner that curbs noise, vibration, and vapor-related wear. As part of the SNP lineup, it shares parts and service procedures with the rest of the range. Capacity extends to 133 GPM, shortening load and unload cycles. Power reaches the pumping chamber through a single-ended keyed shaft turning right-hand, where Duravane vanes ride out against the liner to sustain flow as they wear.
