Texsteam Series 5100 Chemical Injection Pumps
Air or Gas Driven Injectors
Texsteam’s 5100 Series Chemical Injectors are single acting, positive displacement plunger-type pumps, powered by gas via a diaphragm with a spring return. Speed control is accomplished by regulating the exhaust gas discharge flow. Reversal is accomplished by a direct spring-actuated switching mechanism (rotary three-way valve). Volume is controlled by the speed of the pump and by the stroke length, either 1” (25.4 mm) or 1/3” (8.5 mm) lengths.
The 5100 Series is capable of pumping high pressures with gas pressure as low as 8 psig (0.6 bar) and handling volume output up to 30 gallons (113 liters) per day.
The pump is lightweight, compact and contains a minimum of working parts for easy maintenance. Each fluid pump head is equipped with a stainless steel plunger, ball checks, ball check springs, top seat, top bushing, bottom bushing, adjustable VEE type packing and a priming valve. The packing yoke is equipped with a drain to monitor for possible packing leaks. Because of the sealed bearings, the unit is oil-less.
