Pump Comparisons

by Sep 3, 2015Lifestyle, News

Pumps, pesticide pumps that is, are something that is forgotten about once the initial purchase has been made. They sit on the back of your rig and hopefully churn out endless litres with little effort or complaint, and when they don’t they are generally replaced with a similar pump because “that’s what I’m used to”.

In this article we are endeavouring to look at the different types of pumping equipment that is available to the pest technician. Even though you know your pump, it may not be the best pump for your application e.g. a technician that generally only pumps up reticulation systems may only need a high volume lower pressure pump like a fire-fighter. Then there are the technicians that mainly do general pests in rental properties, they may only require a 12v electric type. The 12v unit not only saves money initially but enables the technician todo before or after hours work with no noise pollution issues. Below we have listed some of the pros and cons for different types of pumps used in the Pest Management industry.

Diaphragm Pumps e.g. AR30

AR30 Pump & Honda Engine 1Pros –

  • High Pressure
  • Self priming
  • Can usually run a couple of hoses simultaneously without pressure drop
  • Available in both petrol and 240v

Cons –

  • Higher initial expenditure
  • Requires a higher pressure rated hose
  • High maintenance due to more working parts eg. Diaphragms, pulsators, & valves

Turbine Pumps e.g. Nova

Nova High Volume Pump 1Pros –

  • Very low maintenance due to design simplicity
  • Highly compact design-saves space in vehicle
  • Less expensive than a diaphragm pump
  • Medium pressure Medium volume

Cons –

  • Not all models designed as self-priming (but in practice usually do self-prime)

Centrifugal Pumps e.g. Fire fighter

01HR-H-5012Pros –

  • High Volume
  • Ideal for reticulation pump ups
  • Can be used for general pests, however slightly down on pressure
  • Very cost effective compared to previous pumps mentioned

Cons –

  • Increase in initial plumbing costs due to larger fittings and plumbing area required
  • Most fire fighter pumps will require a Viton kit to be installed
  • Lower pressure than the previous pumps mentioned, does not have the pressure
  • to drive the solution through long lengths of small diameter hose
  • Larger in size than turbine pumps

12 volt Electric Pumps e.g. Shurflo
