High hotwell level will get the cooling water tubes of condenser submerged in the condensate hence cooling efect will be reduced consequentaly vacuum will drop. Low hotwell level will lead to low suction pressure of Condensate Extraction Pump hence it may lead to cavitation.

A vacuum pump is any device which does work to transfer air from one volume to another volume, and thereby reducing the pressure of the first volume. There are several different types of vacuum pumps available, each operating over different pressure ranges.
Oh, dude, Otto von Guericke invented the vacuum pump in the 17th century. It's like this device that sucks out air from a space, creating a vacuum. So, yeah, he basically made it possible for us to understand the concept of a vacuum. Cool, right?
The simplest of pumps. A vaned rotor rotates inside the pump body. The water spins to the outside of the pump rotor and is forced out of the outlet pipe. The differential pressure across the pump continuously reprimes it. Very common in vehicle cooling systems, power showers and in washing machines.
Reasons for low vacuum: 1. Low gland sealing pressure 2. Condenser tubes choked 3. Condenser cooling water temperature high 4. Leakage in condenser tubes 5. Less cooling water flow

An atmospheric condenser operates naturally at atmospheric pressure (1.013bar). A vacuum condenser operates at pressures below atmospheric and will use some sort of pump to provide a vacuum.
Condenser Backpressure is the difference between the Atmospheric Pressure and the Vacuum Reading of the Condenser, that is: Backpressure = Atm. Pressure - Condenser Vacuum Pressure Reading Usually, the condenser vacuum pressure is read by a manometer installed at the condenser. The atmospheric pressure is read using a barometer

Condenser coil
A vacuum pump is used to expel air and non-condensible gases from the condenser in order to allow it to continue accepting steam (the collapse of which produces the vacuum in a condenser). If the vacuum pump fails, it will take from seconds to a few minutes before enough non-condensible gases build up in the condenser to stop the flow of steam. The non-condensible gases come from the boiler feedwater supply, despite the fact that boiler water is treated to prevent this. The minute amount of air in the water is carried with the steam into the turbine then the condenser where it will concentrate unless removed by the vacuum pump.
Typically, it is a Condenser or Heat Pump outside and a furnace and cooling coils inside
vacuum pump helps the brake system to function well when pedal is fully depressed and released.
Air Conditioning Vacuum Pump.
Need to know year, make, engine and model of the vehicle.
The function of a heat pump capacitor in a heating and cooling system is to store and release electrical energy to help start the compressor and fan motors, ensuring the system operates efficiently.
