Injection Pumps and Systems

By listening to the needs of our customers, we have developed and offer a comprehensive pump range utilizing materials such as 31655, ceramics, and Teflon in order to achieve the highest corrosion resistance possible.

To meet the needs of highest accuracy and reduced chemical costs, Haskel pumps offer both stroke rate and stroke length adjustment providing high flow rate turndown ratios, and enabling simple setup and operator adjustments when necessary.Haskel Inte

In developing this extensive range, Haskel has drawn on decades of knowledge and experience in producing high-pressure pumps (up to 100,000 psi) and has built in the technology and high quality that has made Haskel the largest manufacturer of high-pressure pumps in the world.Haskel International, In

Pneumatic Pumps for Chemical Injection

• Intrinsically safe, non-electric
• use of air/gas drive and corrosion resistant materials allow use in difficult and hazardous areas such as offshore oil/gas platforms.

• Positive displacement
• Stroke rate and stroke length adjustment for accuracy
• Materials chosen for maximum corrosion resistance

• Manufactured to the highest quality standards demanded by today's industry
• Compact design compared with alternate electric pumps
• Reduced components for easy maintenance
• Easily installed, easily operated

• Oil, Petrochemical & Refining - Metering and injection of chemicals during the production,   processing, refining or transmission of oil and gas.
• Offshore Oil & Gas - Injection and metering of Methanol, Glycol, corrosion inhibitors,   emulsion breakers, oxygen scavenging, etc.
• Gas LNG, LPG and CNG - Injection of Methanol, corrosion inhibitors and odorants.
• Power Generators - Injection of caustic and other chemicals for prevention of corrosion  and scale in industrial boilers.
• Chemical Processing & Laboratories - Metering of dyes, detergents, lubricants, etc.
• Pulp & Paper - Metering of caustics, solvents, defoamers, biocides.
• Water Treatment - Metering of acids, corrosion and scale inhibitors.
• Industrial - Metering of chemicals and solutions used in the manufacture of paint,   rubber, plastic, ink, textiles, fertilizers, electronics, etc.

Each  injector  or metering  application has  characteristics that  can affect  metering accuracy.  These include fluid compressibility, viscosity,  line length,  etc. It  is therefore  necessary to  select  a  pump  that will  provide both  the pressure,  displacement and  cycle rate  well within  the requirements and adjust the cycle rate under actual site conditions.

This  is  most  commonly  done  by  observing  the  amount  of  time  taken  for  a  known  volume  of liquid to flow into  the pump  (while operating  under full  load if  possible) for  good accuracy.  Simply  observe  the  time  taken  while  the  pump draws  fluid from  a graduated  tube or  container  (rate  gauge recommended  - see  page 10)  and extrapolate  the results  in a  rate per  minute, hour or day as required.Haskel International, Inc. is the world's leading manufacturer of pneumatically driven, high-pressure liquid pumps, gas boosters, air pressure amplifiers, and high pressure systems

• Output per hour -- select the  smallest pump  capable of  achieving the  output flow  rate with-  in  the  maximum  number  of  strokes  per  minute.  (Consult  the  chart  for  maximum  number of  strokes per pump.)
• Outlet pressure available -- select  a pump  nominal ratio  to give  an outlet  pressure greater  than the process line pressure; e.g., if  process line  pressure is  345 bar  (5,000 psi)  Ratio x  Air Drive Pressure = Outlet Pressure 60:1 x 6.2 bar (90 psi) = 372 bar (5,400 psi)
• Chemical  to  be  pumped  -  check the  wetted materials  section table  to ensure  seal pack-  age, pump body, piston, bearings and check valves are compatible with your chemical.
