Pumping station - what is it, its design
Pumping station - a system / set of devices for pumping water and increasing pressure in autonomous water supply systems.
A standard pumping station consists of 5 interconnected elements:
- Electric pump
- Motor
- Hydraulic accumulator
- Pressure switch
- pressure gauge
How does a pumping station work? General concept
The task of the pumping station is to pump water in an autonomous water supply system and increase the pressure in the pipeline. In private houses and summer cottages, there is often not enough pressure in the pipeline. It seems that there is a pump, it works at full capacity, it pumps water, but there is little pressure. In such situations, a pumping station is used. Its working principle is as follows:
The electric pump pumps water from the tap. The liquid fills the entire water supply system - water supply pipes to each consumer, tap. Also, water fills a third of the accumulator. Two-thirds of its internal volume is occupied by air, which is separated from the water by a flexible membrane. Air was pumped into it at the factory, its pressure is indicated on the packaging - most often it is one and a half atmospheres. The pump pumps water into the system until the pressure switch closes. The relay closes only when the pressure in the pipeline reaches 1.5 atmospheres. To measure the pressure in the plumbing system, a pressure gauge is placed on the pumping station. It turns out that air presses on all the water in the pipeline through the membrane, increasing the pressure in the system to 1.5 atmospheres. When water is used, air pushes the water out of the system at the specified pressure. After that, the pump again pumps the system with water.
Advantages of a pumping station Recommendations for the installation and operation of the pumping station
The main advantage of the pumping station is that it does its job - it pumps water and increases the pressure in the pipeline. Additional advantages of the pumping station are simple installation (connect four pipes) and durability (the average service life of factory devices is 8 years).
Pumping stations can operate with clean water at temperatures above 5 degrees Celsius. Otherwise, the pump may become clogged, it will be more difficult for it to pump cold water, and equipment wear will accelerate. Install the water supply pipe to the pump at an acute angle (at least 1 degree). Due to the power of the motor, the suction pipe must be fixed to the wall/ground to a depth of 50 centimeters. The device makes a lot of noise during operation, so it is recommended to place the pumping station on the first floor, in the basement or separately from the main house. Choose the volume of the accumulator depending on the number of people living in the house:
- Two people will need a device with a volume of up to 40 liters
- Three - 40-100
- Four - 100 or more
For suburban areas where water is rarely used, a device with a volume of 15 liters can also be installed.
Top 3 best pumping stations for a private house
QUATTRO ELEMENTI Automatico 800 Ci Deep 645-280
Model of the Italian brand, which is assembled in China. Engine power 800 watts, pumps up to 41 liters per minute. The volume of the accumulator is 20 liters. Pumps water from a depth of up to 30 meters. The water supply pressure is regulated (from 1.5 to 3 atmospheres). Light weight - 20 kilograms. High-quality and reliable assembly materials. Enough for normal operation with six points of water intake.
Marina-Speroni APM 100/25
Due to the cast-iron body, this model can be used even at low temperatures; cast iron also dampens motor vibrations well. The pump pumps water from a depth of up to 25 meters. The pressure is regulated - 1.6 / 3.2 atmospheres. Service life 10 years. Manufacturer's warranty for 3 years. Weighs 27 kilograms. The motor consumes 1100 watts of power. In addition to the fact that the pump pumps water from a depth of 25 meters, it can also raise it to a height of up to 32 meters.
Grundfos MQ 3-35
The device was not equipped with a hydraulic accumulator, but the station can also keep a constant pressure, regardless of the flow rate. The pump pumps water from a depth of up to 8 meters and can lift it to a height of up to 33 meters. The case is made of stainless steel and covered with a powder from corrosion. Suitable for installation in basement/rooms with high humidity. Can work with dirty/rusty water. The pressure is adjustable. There is an automatic dry start protection system. Protected from overheating. Electronic control. 850 watt motor. Pumps 3.9 cubic meters of water per hour.
