Correct
Q: Which of the following isn’t one of the main benefits of the CM pump range?
A: External control
Correct
Q: Which load profile will benefit the most from a demand driven control system?
A: Low flow rate with relatively few peak periods during the day.
Correct
Q: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
A: Intelligent pumps equipped with temperature sensors that measure the outlet temperature and signal the pump to regulate its flow accordingly – without the use of valves.
Correct
Q: How do you prevent pumps from malfunctioning when transporting hot water with a temperature of well above 120C°?
A: Equip the pump with double-shaft seals or air-cooled top.
Correct
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: The viscosity and density of propylene glycol is higher than tap water.
Correct
Q: What is the ratio between the capital investment and running costs of a temperature control system?
A: 1:20
Correct
Q: Why is ammonia an efficient coolant?
A: Ammonia is able to absorb large amount of heat when it evaporates.
Correct
Q: Which component is often ‘the weakest link’ in centrifugal pumps?
A: Shaft seal
