Argal “Astra range” air operated double diaphragm pump or AODD pump is operated by compressed air and is intrinsically safe. It can run submerged in liquid. The body material of construction can be GFR-PP, CFF-PVDF, PVDF, SUS 316, Aluminum, SUS 316 Polished, PTFE, Santoprene and Keyflex. Diaphragm material can be.
ARGALAIR pump is operated by compressed air and are intrinsically safe.
The pump design allows high suction lift even at drystart and with heavier fluids.
If external material are compatible, then the pump can run submerged in the liquid by simply running the exhaust line above the liquid level
ARGALAIR pump can be easily transported to the application site. Simply connect your air supply line and liquid lines and the pump is ready to perform. There is no complex control for installing and operating.
No close fitting or rotating parts so liquids with high solids content can be easily pumped, actually any liquids with max of 90% solids.
Because the discharge pressure can never exceed air inlet pressure, the discharge line can be closed with no damage or wear. The pump will simply slow down and stop.
ASTRA AODD pumps with sizes from ½” to 2” offer incresed flow compared to common pumps of the same size. This translates in an economical advantage for smaller and less expensive pump delivers equal performances or in technical advantage for same pump size delivers same performances at lesser strokes per minute with reduced mechanical stress and wear of all parts. For these reasons the user enjoys longer operational life, lesser LCC ( Life Cycle Cost ) less vibration and attenuated noise compared to conventional pumps.
All ASTRA pumps can be preset to;
Auxiliary connections to implement the a.m. optional features and modes of use are lodged in the technical panel placed near the air exaust.
Hydraulic connections of Astra pumps can be configured accordingly to several schemes;
The standard scheme foresee one manifold with horizontal lateral inlet and one manifold with horizontal lateral outlet;
The optional schemes foresee one manifold with horizontal inlet and one manifol with horizontal outlet, or a mix of the two types
It is a special version fitted with optional suction pipe long up to 2 metres, made of same wet materials as the pump and allows to prime from drums pure and viscous chemicals even in hazardous enviaronment.
