Compressor Priming System

The Sykes Compressor Prime self-priming system utilises a jet of compressed air passed through a venturi-type nozzle to evacuate the pump casing and suction line for fast, positive and continuous priming, even under snore conditions. The priming system has no moving parts, greatly reducing maintenance requirements.

 
Impeller
Stainless steel 316 for best corrosion resistance. 2% Chromium and CD4MCu available as options. Impellers are open for best solids handling, and have back vanes and holes for pressure balancing. 

Venturi Prime
Simple design, easy to clean. Modular for easy parts replacement. The venture system requires very little maintenance, and is easily serviced in the field.  

Volute
Made from Spheroidal Graphite Cast Iron. Spheroidal Graphic iron provides superior strength compared to ductile and gray iron. Spheroidal Graphite molecules prevent cracking in the metal thereby adding to the overall strength of the metal.  

Wear Plates
Replacement front and rear wear plates made from 316 stainless steel. 2% Chromium steel and CD4MCu abrasive resistant steel are available options. Replaceable wear plates lower operation and replacement costs by allowing adjustment of the wear plates as they wear.  

Discharge
Flapper style check valve for deck discharge, or Ball type for top discharge, available.  

Compressor
Water cooled for lower running temperatures, this means a longer life for the compressor and less maintenance on the compressor and venturi system.  

Seal
Oil bath mechanical seals allow dry running for extended periods. The oil bath dissipates the heat and lubricates the seal. Materials of construction include silicone carbide and tungsten carbide for the most effective head and friction coefficient. New seals allow for higher pressures, this means improved performance in flooded suction and series pumping. Seal elastomers include Buna N and Viton.  

Shaft
Made from 431 Stainless Steel means no rust or pitting on the shaft for easier seal changes.
