Blackmer's new transport pump.

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.

The STX1220A can operate at lower flow rates from 42 gpm (159 lpm) to 92 gpm (348 lpm), and is thus suitable for low-viscosity chemical handling. Other key features of the STX1220A Transport pump are a pushrod-free design that allows higher pump speeds from 700 to 1,200 rpm, maximum viscosities of 100 SSU (22 cSt), dimensional interchangeability with Blackmer TXD2 and TXD1220 pump models,  internal adjustable relief valve and three drain ports which allow draining in any mounting position.
