Chemical Resistance of Pump Materials
The recommendations listed on the following page are based upon information from material suppliers and careful examination of available information and are believed to be accurate. However, since the resistance of metals, plastics, and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors, this information should be considered as a general guide rather than an unqualified guarantee. Ultimately the customer must determine the suitability of the pump used in various solutions.

Chemical Resistance of Plastic Resins
The results shown herein are typical results that have been obtained in laboratory tests using bars molded from typical lots of resin. These results are for natural colors only. The addition of additives may alter some results.
In addition, design, processing methods and equipment, environment and other variables may affect actual part performance.

Chemical Resistance of Various Elastomers
The following pages are offered as a general guide and inspection of the suitability of various elastomers in use today for service in these chemicals and fluids. The ratings are based, for the most part, on published literature of various polymer suppliers and rubber manufacturers but, in some cases, they are the considered opinion of experienced compounders. We cannot guarantee their accuracy nor assume responsibility for use thereof. Several factors must always be considered in using a rubber part in service.

GP:50 announces the release of yet another product to further complete their full line of upstream oilfield pressure and temperature transmitters. Working in conjunction with a major well servicing company, GP:50 developed the Model 340-IM series pressure transmitter specifically designed for blender discharge pressure applications. The Model 340-IM resolved the chronic high failure rates they experienced with other suppliers.
Designed for direct pipe mount via its flush process pipe connection the Model 340 series can handle the pressure and harsh media found on Frac blender trucks.
The Model 340 transmitter offers a compact, all welded, rugged design with a flush faced sensor that resists clogging found with conventional pipe mounted transmitters. With at least 5 times proof pressure, and a machined stainless steel sensing diaphragm, it can withstand erosion from aggregate and survive high pressure spikes typically found in blender applications.
With a proprietary sensor design there is zero installation offset, typically found with flush NPT process devices. Available in 4-20mA, 0-5 VDC or Canbus J1939 outputs and pressure ranges from 0-75 thru 0-1,000 PSI.
