  • Flawless operation with the merlin pump from mono nov

    The Merlin progressing cavity pump underwent rigorous tests, alongside air diaphragm, gear and lobe pumps, toensure its suitability for the duty. The low speed Merlin pump has a gentle conveying action to ensure the integrity of the shear sensitive PVC coating. Vigorous action of the gear pumps created too much heat causing the PVC to solidify, and the air diaphragm pumps proved to be very energy ...

  • Submersible Pumps vs. Self-Priming Centrifugal Pumps

    When selecting a centrifugal pump for bypass work, the first consideration should be NPSHR by the pump. Neglecting the NPSHR of the pump is the single most common mistake when choosing a self-priming or priming assisted pump. A function of the pump design requires part of the 33.9 ft (14.7 in.) available as further defined in this article. A centrifugal, and in a way submersibles, require part ...

  • Effects of Slurry pump expeller

    Expeller not only with sealing effect, but also can serve to reduce the axial force. The axial force in the slurry pump is mainly caused by the liquid pressure acting on the impeller and the rotating part of the composition of gravity. So it is easy to know, in the same identical performance parameters, slurry pump axial force is stronger ...

  • Hand-pump subsurface arsenic removal: the effect of groundwater conditions and intermittent operation

    Hand-pump subsurface arsenic removal (SAR) has been investigated in rural Bangladesh with different groundwater conditions and intermittent operation modes. Multiple injection-abstraction cycles were performed after injection of 1 m3 of aerated water. From these experiments it can be concluded that hand-pump SAR, in the traditional injection-abstraction design, does not provide drinking water ...
