How to choose a motor pump
A motor pump is clearly not a device for daily use, so it is better to entrust its choice to professionals. Maxim Sokolov, an expert at the VseInstrumenty.ru online hypermarket, tells how to choose the right motor pump.
First of all, you need to pay attention to the following parameters:
● Performance – shows how many liters of water the equipment will pump over in one minute. The higher this value, the faster the job will be completed. For pumping a large volume of water, it is better to choose a model with an indicator of 1000 liters per minute.
● Pressure, he is the height of the lift, this is the distance that the motor pump can move water. For summer cottages, you can use a model with a value of 30 – 40 m. To work in the fields, extinguish fires and at large facilities, high-pressure equipment is needed – from 70 m. Pressure losses must also be taken into account, that is, hydraulic resistance during water transfer. The longer the sleeve, the less performance will be at its end point.
● Type of power – gasoline or diesel. Here you need to give preference to the fuel that is more accessible to you. It is believed that diesel motor pumps are more durable and economical. But gasoline is more affordable and presented in a wide price range.
