Involves passing a jet of compressed air through a venturi-type nozzle to evacuate the pump casing and suction line. It makes sure priming is fast, positive and continuous - even under snore conditions. The priming system has no moving parts. This greatly reduces maintenance requirements.
System Features and Benefits
Stainless steel 316 for optimum corrosion resistance. Two per cent chromium and CD4MCu available as options. Impellers are open to improve solids handling, and have back vanes and holes for pressure balancing.
Simple design, easy to clean. Modular for easy parts replacement. The Venturi system requires very little maintenance, and so is easily serviced in the field.
Spheroidal graphite cast iron for superior strength compared to ductile and grey iron. This also helps prevent cracking in the metal.
316 stainless steel replacement front and rear wear plates. Chromium steel abrasion resistant and CD4MCU corrosion and abrasion resistant steel are available options. Replaceable wear plate adjustment facility lowers operation and substitution costs.
Flapper style check valve for deck discharge, or ball type for top discharge available.
Water cooled compressors for lower running costs. This means a longer life and less maintenance of the compressor and Venturi priming system.
Oil bath mechanical seals allow dry running for extended periods. The oil bath dissipates the heat and lubricates the seal. Silicone carbide and tungsten carbide for the most effective head and friction coefficient. Seal technology allows for higher pressures, which improves performance in flooded suction and series pumping. Seal elastomers include Buna N and Viton.
431 stainless steel to help prevent rust or pitting on the shaft and make seal changes faster and simpler.
Features a vacuum priming chamber which dramatically reduces carry-over due to the stainless steel baffle deflector plates and pancake float. Ideal for wellpoint dewatering and long suction conditions.
System Features and Benefits
60cfm vacuum prime
Ensures quick priming even in long suction conditions.
Float type head gear
Made from anti-corrosive materials.
Over centre positive latches
For easy access during servicing and maintenance.
Made from spheroidal graphite cast iron. Spheroidal graphite iron provides superior strength compared to ductile and grey iron.
Stainless steel 316 for best corrosion resistance, CD4MCu, and cast iron available as options. Impellers are open for best solids handling, and have back vanes and holes for pressure balancing.
Flapper style check valve for deck discharge, or ball type for top discharge, available.
Replacement front and rear wear plates made from 316 stainless steel. Chromium steel abrasive resistant and CD4MCU corrosive and abrasive resistant steel are available options. Replaceable wear plates lower operation and substitution costs by allowing adjustment of the wear plates to maintain efficiencies.
Oil reservoir and oil/air separator
Fitted and an integral part of the vacumax chamber. The two stage oil separator reduces misting from the vacuum pump exhaust.
Oil bath mechanical seals allow dry running for extended periods. The oil bath dissipates the heat and lubricates the seal.
Made from 431 stainless steel which means no rust or pitting on the shaft for easier seal changes.
