Flowserve SIHI Side-Channel Pumps

CEH |AEH | AKH | AKL/AKV | AOH

Easily pump liquids under vapour pressure as well as pure, turbid or aggressive media, and gas-entrained fluids.

Generating sufficient pressure for long-distance and small pipe pumping, SIHI side-channel pumps provide reliable operation in unfavourable suction conditions. Suited to a wide range of applications, from liquids under vapour pressure to pure, turbid or aggressive media; gas entrained fluids; and numerous applications in the gas & oil sector, they are also used in pharmaceutical, food & beverage, chemical & petrochemical applications; as well as in agricultural, and naval applications.

    Reliably & efficiently handle liquids with as much as 50% vapour

    SIHI side channel pumps from Flowserve combine elements of centrifugal and positive displacement technologies. This means they can separate and independently handle gas and liquid components through distinctly different pathways. Their ability to handle entrained gases results in a highly efficient system capable of handling liquid/gas mixtures with high vapour content. Unlike centrifugal pumps, which can underperform and airlock with as little as 3% entrained vapour, SIHI’s side channel technology accommodates as much as 50% vapour in the suction stream with no ill effects.

    Magnetic drive pumps are ideal for applications in chemical processing, water treatment, pharmaceuticals, and other areas where leak-proof operation is critical.

    More info on our side channel pumps

    Side channel pumps from Liquid Movers are designed for handling various fluids, including aggressive and viscous fluids, and those containing solid particles. These pumps are also referred to as liquid ring vacuum pumps and self-priming multistage pumps.

    Renowned for their ability to create high suction power and handle a wide range of flow rates and pressures, these channel impeller pumps operate using a side channel (or a recess), which captures fluid and then imparts energy to it via centrifugal force. This makes them effective in pressurising and transferring fluids.

    Our side channel pumps are:

    • Versatile: capable of handling a wide variety of fluids, from slurries and chemicals to clean water.
    • Durable: they are designed with robust materials which enables them to withstand corrosive substances and harsh conditions.
    • Compact: they have a compact design which reduces their footprint, making them ideal for places with minimal space.
    • Efficient: they offer a high level of efficiency when transferring fluids.

    They also have high suction capability, which makes them effective in applications that require high suction lift. This means they are suitable when self-priming is required.

    The design and construction of our side channel pumps can vary based on the specific application requirements and the type of fluids that need to be pumped.

    Additional benefits of our side channel pumps

    • Gas handling capability: These pumps continue to function reliably with gas-entrained fluids, with as much as 50% vapour content. This makes them ideal for applications where vapourisation and two-phase liquids are a consideration.
    • Low NPSHR performance: Flowserve side channel pumps boast low NPSHR values. CEH models are capable of operating as low as 0.18 m without cavitation.
    • Self-priming capability: These pumps are self-priming once the body is filled. This eliminates the need for vacuum or booster pumps in the suction lift application.
    • Superior reliability: The self-priming and gas-handling characteristic of side channel pumps ensure safe operation, even with fluids at their vaporisation/boiling point.
    • Steep performance curves: In comparison to centrifugal pumps, these pumps have more consistent flow rates in response to differential pressure or temperature variations. This lowers the pump operating cost while minimising the impact of seasonal and variable discharge conditions.
