CHEMICAL PUMPS - Series 51

The CVS Controls gas driven Series 51 Injector uses a molded diaphragm to drive a piston through the chevron packing making it a positive displacement pump, capable of discharge pressures up to 6000 PSIG.

A rotary switch valve directs incoming operating gas behind the diaphragm, which causes the diaphragm to stroke forward. The valve shuts off the inlet pressure and opens to expel the spent gas behind the diaphragm and the cycle repeats.

A choice of three plunger sizes, two stroke lengths and controllable strokes per minute (SPM) with an optional slow-speed controller allows for a wide range in capacity, from less than one quart to 30 gallons per day.

The Micro Valve unit is a miniature valve offering reliability and rugged construction. With an over-centre, snap action-action operator, the unit consists of a three-way, two-position valve. The unit offers sure response, no neutral position and no varying time lag between positions. The unit maintains either position without holding force, and cannot be vibrated or jarred out of position. The Micro Valve Unit negates any requirement for lubrication in the pump cavity, making this unit environmentally friendly.

The standard fluid end is ductile iron with stainless steel trim and plunger. All stainless steel is an available option.

Applications:

• Introduction of de-emulsifiers, corrosion inhibitors, de-scaling agents, solvents and oxygen scavengers
  
  
• Injection of surfactant (soap) into low-pressure gas wells with high water content
  
  
• Methanol injection in gas pipelines
  
  
• Water treatment
