Blackmer® Launches STX1220A Sliding Vane Pump Line

Blackmer^®, a global leader in positive displacement rotary vane and reciprocating-gas compressor technologies, is pleased to announce the addition of the STX1220A Transport Pump to its growing line of standard-setting positive displacement sliding vane transport pumps. Designed for use in low-viscosity chemical-handling applications, the new STX1220A is a 316 stainless-steel pump that features PTFE mechanical seals compatible with corrosive chemicals.

What separates the STX1220A from other members of Blackmer’s STX line is its capability to operate effectively and efficiently at lower flow rates from 42 gpm (159 lpm) to 92 gpm (348 lpm), which is a major consideration for many end-users who specialize in low-viscosity chemical handling. Other key features of the STX1220A Transport Pump are:

• • Pushrod-free design that allows higher pump speeds from 700 to 1,200 rpm
• • Maximum viscosities of 100 SSU (22 cSt)
• • PTFE elastomers
• • 90-degree porting with weld flanges
• • Dimensional interchangeability with Blackmer TXD2 and TXD1220 pump models
• • Foot-mounting
• • Standard Duravanes
• • Ball bearing construction with PTFE chemical mechanical seals
• • Chrome oxide-coated stainless-steel heads
• • Internal adjustable relief valve
• • Three drain ports to allow draining in any mounting position
