Product Faqs

Ask a Question

  • Q:Which type and size of pump is best for pumping water from a house tank up to holding tanks for gravity feed? I need to pump up the hill to a 15 metre head height over a distance of approximately 100 metres.
    A:

    Hi, it is difficult to advise exactly what pump you need without more information; e.g. what is the uplift from the tank to the pump, how much water you need to move, how quickly, whether the distance between the points is in a straight line, what size are your hoses etc. etc. 

    However, as a rule of thumb, the maximum head capacity of the pump can tell you what the pump can do in terms of; suction height + uplift. For example, if you needed to draw up water 5 metres from the water source to the pump, then move the water from the pump up a gradient of 15 metres, then you would need a pump with a maximum head greater than 20 meters (5 +15).

    Also remember that there will be a small loss of head capacity through general friction, so your first consideration is a pump with head capacity greater than 20 metres, then secondly what flow rate (litres/min) you require - this is where the pump charts come in handy (on the product brochures) as the water flow rate diminishes with the height. 

    Depending on your suction height, I would be inclined to look at a Honda or Subaru powered 2" or 3" Transfer Pump that has a head capacity of around 30-35 metres and flow rate of around 500-600 litres per minute. If your suction height or flow rate requirement is larger, then you'll need to look at a larger pump.   

  • Q:I need a transfer pump to move some water from a flood prone area of my property. How do I know what size pump I need?
    A:

    Hi - great question. There are many variables when transferring water (hose width, hose bending, how much pressure you may want/need, how much water you want to move per minute etc.). However, as a rule of thumb, the Maximum Head capacity of the pump will tell you what the pump can do in terms of; suction height + uplift. For example, if you needed to draw up water 4 metres from the water source to the pump, then move the water from the pump up a gradient of 25 metres, then you would need a pump with a maximum head greater than 29 meters (4 + 25). You should also consider how much water you want to move per minute and how much discharge pressure you may need, this is where pump charts come in handy as delivery capacity falls away as max head capacity is approached.

    The maximum head rating (in metres), and water flow rating (litres per minute) of the water pump is listed under the Specifications of each pump model. 

    As mentioned, there are many variables when considering water transfer requirements and this rule can be used as a good approximate guide. We advise you use this rule and select a pump with greater max head capacity than your requirements to account for other small things such as friction which will also slightly reduce the pump's head capacity.   

  • Q:Based on my understanding of ‘Maximum Head’, would I be right in saying that a pump with a Max Head of say 20m, could transfer water 18m directly vertical, if the suction inlet was 2m above the water source?
    A:

    Yes. That is the correct interpretation of the Max Head capacity of a pump. Note in your theoretical example though, the water pressure and flow rate would be around zero at the discharge point (because the max head of the pump is 20 metres and the sum requirement of your example is also 20 metres). In practice, if you're pumping requirement totaled 20 metres, you would want to get a pump with a max head capacity of greater than 20 metres, to have sufficient water flow and account for small head loss from friction. 

  • Q:When talking about the size of the pump, does that refer to the diameter of the inlet or the outlet?
    A:

    In our range of pumps, the inlet and outlet size of the pump is the same, with the exception of the Fire Fighting pump models. These high pressure Fire Fighting pump models will have one inlet and one transfer outlet the same size which classifies the size of the pump...then most Fire Fighting Pump models will also have two additional outlets which are slightly smaller and are designed for the high pressure discharge.

  • Q:Hi, I’m looking for a pump to deliver water from a creek to a garden area about 400 meters apart; what do you recommend?
    A:

    Hi, our portable pump range (transfer pumps, fire fighting pumps, trash pumps, submersible pumps, chemical pumps) have models that will effectively handle pumping vertical distances from about 20 metres up to about a maximum of around 90 metres - this is the Maximum Head capacity rated on every pump's specifications. 

    The Maximum Head rating will tell you the maximum height the pump can pump to. So you need to know how much height you will need to draw from the water source up to the pump (suction height) and how much height you will be moving the water (uplift). For example, if you needed to draw up water 5 metres from the water source to the pump, then move the water from the pump up a gradient of 25 metres, then you would need a pump with a maximum head greater than 30 meters (5 + 25). Also note that as water moves through the hosing and the bends it will encounter friction, causing some small additional head loss - so you should need to choose a pump with maximum head larger than your height pumping requirements. Then you'll need to consider what flow rate you want to move the water at...this is where Pump Charts are important to consider (see product brochure) because delivery capacity falls away as max head capacity is approached.

    Overall, work out your suction height + uplift, then choose a pump with max head capacity to more than handle the sum of those heights, and a pump that satisfies your flow rate requirements. 


  • Q:Can you transfer saltwater through a standard Transfer pump?
    A:

    Hi, a standard transfer pump is not designed to transfer salt water. We are aware of people that do use standard transfer pumps to move salt water, but if they are not flushed thoroughly with freshwater after use (which often they are not), then the seals will be damaged and corrosion is likely to occur. This damage would not be covered under warranty.


    You would need to look at a Chemical Pump which are built with stainless steel heads, fasteners and shafts, along with viton seals. These pumps are specifically designed for pumping waste water, chemicals, sea water, fertiliser and other caustic liquids.
