Product Description

Comfortably spray high height trees, as well as perform a range of other high pressure agricultural spraying tasks, with the Annovi Reverberi AR813 Diaphragm Pump.

Two models available:

  • Annovi Reverberi AR813-C/SP Diaphragm Pump with 1-3/8" splined thru shaft
  • Annovi Reverberi AR813-GR-CPC-GCI Diaphragm Pump with AR1639 Gearbox and VDR50 Control Unit

The high pressure and high flow rate generated by the Annovi Reverberi AR813 Diaphragm Pump make it well-suited for high height tree spraying applications, but it also finds great use for landscaping, agricultural spraying, vineyard and orchard spraying, petrochemical ,wastewater, mining, printing, and much more.

The rugged and durable design on these three diaphragm pumps make handling strong agricultural chemicals easy. Some of these fluids include herbicides, pesticides, insecticides, fungicides, liquid fertilizers, and other hard-to-handle fluids.

Some other features include a newly-designed diaphragm cut-out system that prevents contact tearing even in heavy-duty operating conditions, pistons with rings for a more efficient oil cushion system, and spherical sector profile valves for lower flow resistance and improved volumetric efficiency. Includes air-hydraulic damper for smoother operation and less hammer effect in the delivery circuit.
