RVP-Series pumps are rotary vane type, self-priming, provided with integral by-pass valve to protect the pump and system against overpressure. The sliding vane pump consists of a rotor turning inside a cam that is machined eccentrically in relation to the rotor. As the rotor turns, the liquid that is trapped between the rotor, cam and vanes is displaced. The RVP Series pumps are made with vanes produced from advanced polymers which exhibit extremely low coefficients of friction. The self adjusting vanes compensate for wear and help extend the life of the pump. Originally designed for fuel and light petroleum products applications, SAMPI RVP pumps are also available in special executions for industrial and chemical products like solvents, resins, inks and so on. Due to its efficiency this kind of pump can handle viscous and also volatile liquids and requires less horsepower than other equivalent pumps.

Grand Rapids, MI – January 29, 2013 – Blackmer®, is a global leader in positive displacement and centrifugal pump, and reciprocating compressor technologies, is pleased to announce that its Model LB601 Reciprocating Gas Compressors possess the operational capabilities needed to meet the challenges of LPG transloading applications. As oil and natural gas production continues to grow, the transport of LPG via railcar also grows in frequency. This makes the transfer of LPG from railcars to storage facilities or transports an increasingly important link in the LPG supply chain. With that in mind, transloading is a more cost effective and increasingly popular way to transfer LPG. Blackmer LB601 compressors are ideal for this critical transfer process because they are equipped with high-efficiency, hardened steel valves, ductile-iron cylinders, PTFE piston rings, self-adjusting PTFE piston rod seals and a pressure-lubricated power frame. This robust design allows the compressor to operate continuously for many hours without fail. When vapor recovery is performed, it can re-claim up to an additional 3% of product volume to every load. The compressor is also able to deliver a flow rate that approaches 300 to 325 gpm, which results in more cost-effective offloading times. Blackmer has created a Video and Case Study that show how CHS Inc., one of the 10 largest suppliers of LPG in the U.S., is using the LB601 compressors as a critical component on an innovative mobile LPG transloading unit that is able to drive from site to site to offload waiting LPG railcars into transports efficiently and cost-effectively.

In a piping system a Expansion joints alternately known as Bellows are like sealed springs. Sealed because it is required to contain the fluid pressure which is flowing through it and spring because it is required to respond to the movement of the connected piping without offering appreciable stiffness to the piping system. An expansion jointbellow element employed in a piping system is an assembly of generally more than one convolute in series. The convolutes are designed strong enough to withstand the internal pressure of the system, at the same time the typical contour of the convolute assembly allow sit to flex under thermal movement of the connected piping. As a result of this extreme flexibility the expansion joint bellow as such is highly incapable of absorbing any longitudinal loads by its own there by requiring external attachments to transfer these longitudinal loads to its connected piping for maintaining the overall stability of the piping system under question.
