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.

NAMCO Snap-Lock®

Snap-Lock® Technology Is What You Need

The SNAP-LOCK® Technology is what makes our remote indication devices so unique. Utilizing this technology in our design enables us to produce a robust, highly reliable and trusted product for the nuclear & power generation industry.

SNAP:
Our solutions have a “snap” action which enables a quick action from one position to another, effectively elimi­nating deadband. The contacts are forced to be in one position or the other and cannot dwell in between open or closed.

LOCK:
Instead of relying on spring or magnetic force, each switch has a locking mechanism that mechanically forces the contacts to stay closed until released by the trip lever. This eliminates any possible contact chatter due to vibration or seismic events.

NAMCO utilizes three different SNAP-LOCK® mechanisms (Cam Type, Rocker Type and Magnetic Prox Type) detailed in the drawings below. The type of mechanism selected is based on your application.

NAMCO Position Indication Switches with SNAP-LOCK® technology are used throughout the power generation industry for a variety of critical applications.

  • Valve Position Indication: From the MSIV to Balance of Plant
  • Actuator Position
  • Conveying
  • Over Travel Protection
  • Overhead Cranes
  • Mobile Equipment
  • HVAC Dampers
  • Presence Detection
  • Door Closure

VTU Series AC/DC Voltage Transducer


VTU SERIES:

High Voltage DC/AC Voltage Transducer

The VTU series of voltage transducers provide very high accuracy and safety in a panel or DIN rail mounted housing. One sensor design can measure DC or AC circuit voltages to 1200 volts, and produce an analog signal directly proportional to the voltage connected.
vtu-voltage-transducer-400x383A very valuable tool to spot issues with power generation (conventional and alternative sources) like brown outs and
phase loss. The voltage will be present on the line side of a disconnect even when the breaker or switch is open. Continue reading VTU Series AC/DC Voltage Transducer
