Pitting corrosion
Pitting corrosion is a localized form of corrosive attacks. Pitting corrosion forms holes or pits on the metal surface.
Plate heat exchanger
A plate heat exchanger is a heat exchanger that is used to transfer heat from one fluid to another.
Power curve
The power curve shows the power consumption of the pump at a given flow.
Power factor
The power factor is the phase angle between voltage and current (cosφ)
Pressure
Pressure is used to circulate liquid in a heating or cooling system and is induced by means of pumps. The pressure in a system is positive in relation to atmospheric pressure.
Pressure boosting system
A pressure boosting system is designed to increase low pressure in a water system in order to achieve sufficient water flow and pressure to consumers.
Pressure holding
A system for maintaining a constant static pressure is used in heating and cooling systems to order to ensure uninterrupted operation.
Pressure holding pumps
Pressure holding pumps are be used to maintain a constant pressure in a closed heating or air-conditioning system.
Pressure reducing valve
A pressure reducing valve measures the pressure of the discharge side of the valve. Its task is to hold the set pressure constant.
Pressure transducer
A pressure transducer is fitted in a heating-, cooling-, or ventilation system. It measures the pressure in a specific location in a system and converts it into a signal which can be read by an instrument.
