The pumps feature an adjustable relief valve, weld flanges and are self-priming. The STX3 has a versatile mounting bracket. Application Typical applications are solvents, chemicals, sulfates, vegetable oils, urea and many acids. The STX3 offers flow rates up to 250 gpm (946 L/min) with differential pressures up to 125 psi (8.6 bar) and maximum speed of 800 rpm. The STX1220A offers flow rates up to 88 gpm (333 L/min). Benefit Blackmer's STX3 offers fast fluid off-loading. A typical off-loading of a 6,000 gallon (22,700 liter) tanker can be unloaded as quickly as 24 minutes. Blackmer's non-metallic vanes self-compensate for wear and allow the STX Series pumps to run dry for short periods of time for self-priming and blowing lines clean, with out pump damage. The STX Series is designed to offer easy maintenance because the internal wear is limited almost completely to the sliding vanes, which can be replaced with ordinary hand tools.
