The need for selfpriming systems
Extracting air from a suction turbine of a not selfpriming pump
A self-priming unit extracts air from a suction turbine of a not self-priming pump. Provides an opportunity for a centrifugal pump, with its advantages of simplicity, reliability, long life and good hydraulic performance, becoming a self-priming pump. SANDE Y DÍAZ has AZCUE priming equipment which are automatic operation, with independent self-priming liquid ring pumps, air ejectors or portable systems for use in main pumps of any brand.
They are liquid ring pumps, high suction power - up to 8 vertical meters - made of bronze, with stainless steel shaft, fitted with filter and check valve.
The VP ejectors require only compressed air to operate. The supply air flow is accelerated to
circulate inside the ejector creating a vacuum, and thus a removal of air from the suction pipe which pump connects.
It is also systems with pumps having a 25 liter boiler steel for water recirculation functions. These autonomous systems allow continuous operation.
Typical applications of these systems are those where a fully guaranteed operation of the main centrifugal pumps is desired, either for liability services or after long periods of inactivity, such as:
Fire fighting services
All kind of marine applications
Water capture in aquaculture, refrigeration facilities, ice factories, etc.
Water supply in general
Ballast and bilge
