Performance for item TXDI2.5A

At 400 RPM and 50 psi differential pressure, the TXD2.5/TXSD2.5/TXDI2.5 pump requires 690 lb-in (78 N·m) of shaft torque with a fluid viscosity of 10,000 SSU.

At 520 RPM and 50 psi differential pressure, the TXD2.5/TXSD2.5/TXDI2.5 pump delivers 95 gpm (360 lpm) of a fluid in the 100 to 5,000 SSU range.

Item Overview for Blackmer TXDI2.5A
The Blackmer TXDI2.5A is a 2.5" ductile iron double-ended, truck-mounted sliding vane pump made for fast, quiet operation and versatile fluid transfer applications. It moves product at rates up to 157 GPM while keeping pressure consistent. The drivetrain pairs a double-ended drive shaft with Duravane vanes, keeping volumetric efficiency stable between rebuilds. Mechanical seals work alongside FKM elastomers to contain aggressive media and resist chemical attack. Installation stays simple thanks to NPT connections that match common piping practice. 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 extended dry-run capability. As part of the TX lineup, it shares parts and service procedures with the rest of the range.
