Pneumatic pump

Series 1200 Beam Driven Chemical Injection Pump

Designed specifically for operation on a beam pumped oil well, the Texsteam Series 1200 Chemical Injection pumps are positive displacement type pumps powered by direct connection to the movement of a walking beam, rod line or rocker arm. The connection is made by a length of nominal pipe, or a wire line. The unit pumps on the upstroke of the beam action. On the downstroke, the injector arm returns to its set position. The ratchet mechanism is housed in a precision-bored, heavy cast gray iron case and is submerged in oil for long life.

The pump head design is efficient because of the horizontal plunger and vertical check valves; virtually trouble-free; easy to maintain; has stainless steel trim in standard heads; and a built-in to aid in priming, check pump action and catch chemical samples and external packing gland.

Series 5000 Texsteam Pump

Texsteam Series 5000 chemical injection pumps are positive displacement units powered by an integral gas/air motor. These pumps fill the requirements of a broad range of applications because of their ability to achieve high discharge pressures (up to 12,000 psig) and wide volume ranges. A horizontal plunger and vertical check valve arrangement provide high operating efficiency.


  • Introducing detergents in air-gas drilling operations
  • Blending foaming agents in water laden gas wells
  • High pressure addition of fluid compounds in blending and chemical processing
  • Introduction of de-salting agents, de-emulsifiers, inhibitors and flocculants in crude oil and gas steams
  • High and low pressure lubrication systems
  • Methanol and alcohol injection in gas systems to prevent freezing
  • General high pressure injection applications

Series 5100 Chemical Injection Pumps

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 introduction of de-emulsifiers, solvents, corrosion inhibitors, de-salting agents and flocculants in oil country operation
  • High pressure bearing lubrication
  • Water treatment
  • Blending processes in refining and process plants
  • Injection of methanol in gas pipelines
  • Hydrostatic testing



Series 6100 Gas/Pneumatic Driven Injection Pumps

The Texsteam 6100 Series Pump line consists of a series of basic pump options all developed from a modular power unit. All units are pneumatically driven positive displacement, single or double acting, reciprocating pumps.

The basic pump is designed for use with three fluid ends, a 1-1/4″ and 2-3/4″ diameter plunger and a 4″ diameter piston. The fluid ends are interchangeable with the modular power cylinder and can be assembled as single ended units or double ended units in all combinations of sizes. All fluid ends are designed to withstand maximum output force of the power cylinder.

eries 9000 Gas/Pneumatic Driven Double Diaphragm Utility Pump
