Product Usage Instructions:

Guidelines and General Information
Before operating the pump, please ensure the following:

Centrifugal pumps are not self-priming.
The pump casing must be filled with liquid before starting.
Avoid pump cavitation by never running the pump dry.
Ensure no restrictions in the input flow to prevent cavitation.

Priming the Pump:
To prime the pump:

Ensure both the inlet and outlet are open.
Confirm valves are fully open for free liquid flow.
Consider installing a sight glass or bleed valve for air removal.

Starting/Stopping the Pump:
To start or stop the pump:

Prime the pump first.
Press the start/stop button on the VFD.
Use the potentiometer knob to adjust speed.
Press start/stop again to end pumping.

FAQ

Q: What is pump cavitation?
A: Pump cavitation is the formation of vapor bubbles in a liquid due to low pressure, causing damage and noise in the pump.
Q: How to prevent pump cavitation?
A: Ensure proper priming, avoid running the pump dry, and maintain unrestricted input flow to prevent cavitation.

OPERATION MANUAL
Congratulations on your purchase and thank you for selecting the Blichmann Engineering Pro Brewing 1 HP Pump Cart ! We are confident that it will provide you years of service, as you continue to craft many gallons of outstanding beer. This manual will familiarize you with the recommended operational procedures and general pump information.

Guidelines and General Information

Before operating the pump, please familiarize yourself with the below:

Centrifugal pumps are not self-priming!
The pump casing must be filled with liquid before its started, or the pump will not function correctly.
If the pump head becomes filled with vapors or gases, the impeller will be air-locked and incapable of pumping.

CAUTION: NEVER RUN THE PUMP DRY. CRITICAL COMPONENTS OF THE PUMP WILL LIKELY BECOME DAMANGED IF THE PUMP IS EVER OPERATED WITHOUT FLUID DUE TO THE LACK OF LUBRICATION. THIS IS COMMONLY CALLED CAVITATION, AND THE PUMP WILL MAKE LOUD AUDIBLE NOISES.

Restriction Flow of the Input:
Other possible causes of cavitation to watch for are restricting the flow of the input.

The input should never be restricted.
An appropriately sized hose feeding the inlet of the pump is important to ensure it maintains the proper amount of flow coming into the pump.
Keep in mind that once the pump begins to flow it will pull the liquid in.
To prevent inlet restriction, a hose larger than or equal to the inlet diameter of the pump is required. WARNING: USING A VALVE TO THROTTLE THE INLET OF THE PUMP CAUSES CAVITATION.

USE A VALVE ON THE INLET OF THE PUMP TO RESTRICT THE INLET.

Priming the Pump:
The process of filling the pump with liquid is called “priming.” Priming the pump and venting the pump housing before startup should prevent gas buildup.

To prime the pump, make sure the inlet and outlet are both open. Hoses usually are attached to both sides.
Make sure the valves are fully open so liquid can flow freely in and out of the pump.
Many brewers will put a sight glass on the output of the pump to ensure it fills with liquid before starting.
You can also install a Tee fitting and valve on the output of the pump to bleed the air off or “bleed valve,” which ensures that you will not have pump cavitation on startup.

TIP: THE PUMP SHOULD ALWAYS BE LOWER THAN THE SOURCE OF THE FLUID IT IS PUMPING. THIS WILL HELP TO ENSURE IT DOES NOT RUN DRY, AS GRAVITY FEEDS THE PUMP.

Starting/Stopping the Pump:

To start up the pump, once it is primed, press the start/stop button on the variable frequency drive or the VFD (as pictured below).
To control the flow, you the potentiometer knob to raise or lower the speed. It is advisable to start with a lower flow rate and increase once the fluid is moving. The speed will be displayed in ROM on the display and can be adjusted without the pump running.
When pumping is complete, press the start/stop button.
