Frequently asked questions about the Water pumps category
Water pumps — what are they and what are they used for?
Water pumps are electromechanical devices for moving clean and dirty water in domestic and agricultural systems. The store offers borehole, well, submersible and circulation pumps for irrigation, home water supply and heating, including automatic models and filtration-capable units.
How to choose a water pump for a borehole?
Pick a submersible or surface pump based on borehole diameter, flow rate (l/min or m3/h) and head (m). Models like LEO EKJ-602I/602IA (600 W) suit shallow boreholes; the automatic variant starts/stops based on pressure for hands-free operation.
Which pumps are suitable for watering garden and lawn?
Surface and self-priming garden pumps with flow rates around 20–60 l/min are ideal for irrigation. Examples in the catalogue are AL-KO HW 3600 and LEO EKJ-802IA (800 W) automatic models, capable of running sprinklers and hose outlets reliably.
Which models have automatic start and how does the automation work?
Automatic models include LEO EKJ-602IA, EKJ-802IA and EKJ-802IA5; their automation switches the pump on/off based on pressure drop and prevents dry running. These units typically include a pressure switch and flow sensor for hands-free operation.
Which pumps suit home water supply and heating?
Choose circulation or centrifugal pumps that deliver steady flow and head. For heating, circulation pumps such as KIERTOVESIPUMPPU 180mm DN25 are suitable; automatic LEO EKJ-series pumps work well for domestic water supply.
Which pumps are suitable for dirty water and flood drainage?
Use drainage and combined submersible pumps with large passageways like the AL-KO DRAIN 9500 Easy 300 W or Scheppach DWP750. These handle suspended solids and are designed for puddles, basements and meltwater.
How do vibration pumps differ from centrifugal pumps?
Vibration pumps (e.g. MVP200 200 W) are compact and simple, suited for shallow lifts but deliver lower flow and shorter service life. Centrifugal and submersible pumps provide higher flow and steadier head, better for irrigation and boreholes.
Which specifications to check before buying?
Check motor power (W), maximum flow rate (l/min or m3/h), maximum head (m), water type (clean/dirty) and whether automation is included. Also note outlet/inlet thread size (e.g. 1") and if a foot/footvalve is supplied.
What head and flow are needed to water 0.5–1 ha plot?
For 0.5–1 ha you typically need 30–120 l/min flow and 20–40 m head depending on sprinkler type. Choose a pump with power margin—800 W LEO-class pumps are often suitable when running multiple zones.
Which accessories are needed and supplied with the pump?
Common accessories include a suction hose with foot valve (4–7 m), adapters and mounting hardware. LEO models frequently come with 4 m or 7 m 1" hoses fitted with a foot/strainer valve.
