How do I know which pump to start first?

If the system is designed for parallel pumps, determine which pump is the stronger one by running one at a time and measuring the head at various flows. As a general rule, always start the weaker pump first.

How do I set up a two-pump system?

If you have a two-pump system, the first step is to determine how the system is designed: Two pumps set up to run individually and/or in parallel. In other words, pumps can run in parallel or separately, covering a wide range of expected flows. Two pumps set up with one pump as an installed spare.

How to start two pumps at the same time?

When running one pump for small loads and then starting the second pump to pick up larger loads, do not let the first pump run out on its curve too far before the second pump is started. The first pump may be cavitating for some time before the second pump picks up. I see this happen often on systems designed to operate automatically.

How do I start my vacuum pump?

Start your pump. After you are sure everything has been securely connected, use the switch device on your vacuum pump to turn it on. You should be able to hear the vacuum running once it is switched on. If you are trying to start the pump in cold weather, open the intake ports until the pump reaches normal running speed. Then, close it off again.

How do you start a power pump from the start?

Pump Start-up Procedure 1 Line up the pump valves. 2 Ensure that the drain valve is closed. 3 Open the suction valve. 4 Open the vent valve to bleed off gases – when liquid comes from the vent valve – close it again. ... 5 Open the gland-seal valve (if fitted). 6 Commission the bearing and oil cooling systems (if fitted).

How do you determine what pump you need?

If anyone tries to tell you what pump you need without establishing what your needed flow (GPM or l/m) and pressure (PSI or bars) are they are just guessing. That’s like determining how many marbles it takes to fill a jar.

When should I start pumping?

If this is your first go-around with pumping, you might be wondering when you should start. “If the baby is healthy and gaining weight well, and there is no anticipated need for separation, it is recommended to wait to use a pump until around 6 weeks old, instead using hand expression to remove any excess milk,” says, Jaimie Zaki, IBCLC, MCD, MCPD.

What should I do before starting my centrifugal pump?

Every centrifugal pump must be primed, vented and full of liquid before it is started. The pump you are about to start must be properly vented and primed. The suction valve must be fully open.

How do you oil a vacuum pump?

Unscrew the oil fill cap, typically located on the top of the pump, and look on the interior edge of the opening for the fill line. Fill the opening with oil until it reaches that line. Then, replace the oil fill cap. Be sure to only use oil meant for vacuum pumps. Using other mechanical oils could impact the quality and performance of your vacuum.

How do you run a vacuum pump with the ballast open?

Running the vacuum pump with the gas ballast open so that the solvent will boil out of the pump when it hits the hot oil is advantageous. In this case it is recommended that a non-restrictive outlet line be installed.

How do you start a vacuum pump in cold weather?

If you are trying to start the pump in cold weather, open the intake ports until the pump reaches normal running speed. Then, close it off again. Open the side gauge valve. Once your vacuum is on, you will need to open the gauge valves, located on the side of each gauge.

How do I know when to change the oil in my vacuum?

Then change the oil according to the manufacture’s schedule or if it looks dirty or smells bad. Rule 2: Warm up the pump with the inlet blocked. By running the pump for 20-30 minutes with the inlet blocked before connecting to your vacuum application, fewer vapors will condense in pump oil.
