Subtor specializes in the production of progressive cavity pumps and we are glad to share with you thorough information regarding these outstanding pieces of equipment. In the following sections we will provide you with detailed material in regard to these pumps. By the time you finish reading the material, you should have a strong idea of which progressive cavity pump you will need for your application. We can also assist if you have further questions.
  • Progressive Cavity Pump Introduction
    Progressive Cavity Pump Introduction

    Progressive cavity pumps are displacement pumps that feature an interference fit on the rotor in eccentric motion. The pump features a fixed stator and a seal cage can be formed inside the pump to move from the inlet end to the outlet end. This completes the media conveying within the seal cage.

    During use, the dry running can result in catastrophic damage to the stator and rotor in seconds. To avoid this, Subtor has designed a water inlet with a suction chamber. This injects water or other liquids into the pump in order to prevent damage during initial use or when restarting the pump. The water inlet can also be used to exhaust air to ensure the flow of media.

    Packing seals are preferred because of the simplicity of their design. They are typically applied in pumping conditions with lower demands and for conveying media with low temperature and minimal corrosive properties. They are used in pumps designed for transporting mud cake, slurry, solid control plants, oily sewage, and other low demand mixtures.
