Pumps type A-VP10 (VS4)
A-VP10 (VS4) pumps are vertical, single-stage submersible pumps with a transmission shaft and a discharge pipe extending outside the immersion zone. Depending on the pumped liquid, the pump design is equipped with a closed or semi-open impeller.
Construction type A-VP10 manufactured in accordance with the latest edition of the API610 Standard (ISO 13709) and the ATEX directive. The A-VP design is an alternative “lighter” design produced on the basis of standards and pump designs according to PN-EN ISO 2858 and PN-EN ISO 5199. These pumps are widely used in various industries.
Layout & Construction Principles
Submersible Vertical Architecture
Centrifugal, single-stage, vertical submersible pumps, separate discharge pipe and shaft guide pipe. The spiral pump body is divided in a plane perpendicular to the shaft line, the suction port is located in the pump axis and is immersed in the pumped liquid, the discharge port connected to the discharge pipe is directed radially upwards along the shaft axis.
Shaft Guidance & Flexible Sealing
Depending on the application, the structure may be equipped with closed or open rotors. The pump shaft (split or not) placed in the guide pipe is guided in bushings which, depending on the pump operation, are lubricated with the pumped liquid or from an external source. The design of the pumps allows for various configurations with or without sealing.
