  • Top 10 Reasons to Choose a Diaphragm Actuated Control Valve

    Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This frequently requires miles of piping mains along with pumps systems and controls that all have to be monitored and controlled somehow. Whether this control is to regulate pressure, a level or a flow, this usually will require some form of a ...

  • Pumping at Subzero Temperatures

    Pumping of cryogenic (low-temperature) products is important for many applications, especially in the field of liquefied natural gas (LNG). The Sulzer J-unit is a special sealing system for cryogenic pumps. It was invented more than 60 years ago. The evolution of the J-unit design since then has been impressive and has now resulted in a recently filed patent application by Sulzer. ...

  • Magnetic driven pumps in Molten sulphur service case study

    MD51EFDKR-3U88/06C with NORD SK12XZ-140TC and Reliance 2 HP, TEFC-XE motor Pumping Molten Sulphur is most challenging. Sulphur temperatures must be controlled within a 120-155o C range. Outside this temperature sulphur solidifies. Sulphur has a distinct odour and is highly corrosive in the presence of moisture. Where leakage from common packed style pumps was unacceptable, a ROTAN ...

  • Large Diameter Impellers Make Trash Pumps More Versatile

    The introduction of these impellers allow for a higher range of discharge pressure. Pumps are available in many types—diaphragm, positive displacement and progressive cavity—but the most common is a centrifugal pump. Centrifugal pumps have an impeller that spins, transferring energy to the fluid by centrifugal force and directing the water to the discharge point within the ...

  • Sizing and Selecting the Proper Metering Pump: Part 1 of 2

    A typical agriculture or process application can consume large amounts of chemicals during daily operations. While the volumes may be large, though, they must also be very precise, with exact amounts delivered according to strict injection schedules. The pressures—from very high to very low—that the chemicals are injected at must also be governed precisely. This demand for ...

In the past, the corrosive nature of the ...

  • Transient and surge related pipe bursts, water loss and damage prevention

    Pipe bursts as a result of transients and surges within a piping network are very common problems throughout the world. Not only are the maintenance costs of these repairs extremely expensive, but when you add in possible litigation for third party damages, combined with the potentially significant value (cost) of the lost water, you can quickly realize the significance of what may appear simply ...
