  • Improved Pump & Seal Reliability & Where It Really Counts
    Poor mechanical seal reliability in the old pumps created serious risks when the sealed lift station was under flood waters.
  • Effective Sealing for Pumps with Elastomers
    Pump users demand maximum operating efficiency from their investment and sealing solutions have to be designed to function between long service intervals. These conditions often create increased chemical, thermal and pressure related stresses on both the pump and seals, multiplying the risk of seal
  • Using Polymeric Rotary Shaft Seals? How to Plan for a Successful Project
    There are often misconceptions surrounding the availability of contacting, polymeric rotary shaft seals. Much of this misunderstanding comes from assumptions made by comparing contacting, polymeric rotary shaft seals to hard-faced mechanical pump seals. Pump seals are readily available as "off
  • Seal-less Resin Pumps
    Synthetic resins play a major role in product production within many industries. Handling resins requires pump technology that will not leak, such as that offered by EnviroGear (R) Seal-less Internal Gear Pumps.
  • Diaphragm Pumps Enhance Chemical Injection Systems During EOR
    To function at maximum efficiency, a chemical injection system must employ a reliable chemical pump that can inject chemicals into the reservoir properly and consistently. Today, many systems use chemical pumps that do not deliver the desired results. Root causes include pump seal failure
  • Types of Fluoroelastomer Seals for Pump Users
    Aggressive pumping environments can be problematic for pump engineers. On one hand it's impossible to design a pump to be resistant to every type of chemical, while on the other, the tendency is to over specify a perfluoroelastomer to cover all eventualities or select an elastomer with mid-range
  • The Great Debate: Sealed vs. Sealless (Pumps & Systems reprint : February 2006)
    applications that can go either way, based on user preference. If lowest initial cost is critical, then sealed pumps sometimes look more attractive.
  • Pump Basics
    a hermetically sealed chamber provided with an inlet and an outlet(cochlea or volute). The impeller is the rotating element of the pump that converts the motor's energy into kinetic energy (the static portion of the pump, i.e. the volute, instead converts kinetic energy into pressure energy
