Achieved badges:
01.
Q: What is the purpose of a booster pump?
A: To increase water pressure
01.
Q: What is the purpose of a booster pump?
A: To reduce lime sediments in steel pipes
01.
Q: What is the purpose of a booster pump?
A: To increase water pressure in plate heat exchangers used for hot water production
02.
Q: What are the benefits of an IE4 motor?
A: Fitted with a frequency drive the motor can adjust its speed to demand to lower energy consumption and wear
02.
Q: What are the benefits of an IE4 motor?
A: The motor has all-magnetic bearings
02.
Q: What are the benefits of an IE4 motor?
A: The motor has a built-in delta P sensor
03.
Q: Does a zone divided system require pressure relief valves?
A: No
03.
Q: Does a zone divided system require pressure relief valves?
A: Yes, if the pressure from the main exceeds 10 bar
03.
Q: Does a zone divided system require pressure relief valves?
A: Yes, they will serve as a safety valve in case of pump failure
04.
Q: Where are the booster sets in a zone divided system placed?
A: In the basement of the building
04.
Q: Where are the booster sets in a zone divided system placed?
A: Next to the tap at the critical spot
04.
Q: Where are the booster sets in a zone divided system placed?
A: In a pit right in front of the building
05.
Q: How is it possible to make sure that an entire system performs at the best efficiency point at all times?
A: An intelligent controller
05.
Q: How is it possible to make sure that an entire system performs at the best efficiency point at all times?
A: Correctly sized pipes
05.
Q: How is it possible to make sure that an entire system performs at the best efficiency point at all times?
A: The right number of pumps
06.
Q: What is the benefit of a booster pump with variable speed
A: The pump automatically adjusts to changes in the water consumption to keep energy usage as low as possible
06.
Q: What is the benefit of a booster pump with variable speed
A: A pump with variable speed is less noisy
06.
Q: What is the benefit of a booster pump with variable speed
A: You can easily increase pressure in case of sediment build-up in pipes
