FAQ - pumps
Here we have prepared answers to the most frequently asked questions regarding the selection or operation of pumps.
What exactly is a pump and how does it work?
Is it always necessary to monitor the level?
This is at the discretion of each customer. Just because your well hasn't dried for five years in a row doesn't mean it won't happen for the sixth year. Therefore, level monitoring can always be recommended and should be included in any installation.
Is the pump better at 230V or 400V?
Nowadays, the myth that the 400V motor has a longer service life than the 230V one practically ceases to apply. In recent decades, 230V motors with their reliability compared to motors at 400V. In some cases, they have surpassed them considerably. Therefore, if you have the option of connecting both 230V and 400V pumps, for simpler connection, it can be recommended rather to 230V.
Is it possible to use a bore hole pump in a well?
When to use a submersible and when a surface pump?
Why use state-of-the-art circulators when I buy another for half the price?
The purchase of the most modern circulator always pays off in the end. Leading manufacturers of circulators meet the European Union's strictest energy efficiency requirements for circulators. Thanks to newly integrated technologies (e.g. motor with permanent magnet, automatic adjustment of the control curve), consumption of these pumps decreases significantly. The price difference between a cheap and a modern pump usually returns very quickly.
Why use energy efficient pumps?
Do you still sell hand pumps for the well?
Nowadays, there are quite a lot of places where no electricity is introduced. Hand pumps have always been and will be part of our assortment.
Can I use 1/2” pipe for pump displacement when pump displacement is 5/4”?
Pump manufacturers usually adapt the discharge orifice to the pump flow. Generally speaking, one dimension smaller pipe can still be used (depending on the length). But definitely not to reduce from 5/4“ to 1/2“. 5/4“ displacement indicates a flow of approx. 30 – 60 l/min., which cannot be pushed through a 1/2“ pipe. Never unnecessarily reduce the pipe to a smaller one. You will deprive yourself of the amount of water and most likely destroy the pump's electric motor over time.
What pipe diameter should I use for pump suction?
It is always the case that the diameter of the suction pipe must not be smaller than the diameter of the suction hole on the pump. If the pipeline is larger, the better.
