Industrial Pump Setting Up Guide
Welcome to industrial pumping – a reliable and efficient choice for your freeze-drying needs. Our industrial pump, known for its quieter operation and less frequent oil changes, offers both durability and convenience. Let's get started on setting it up!
Industrial Pump Options:
- Steel Wire Reinforced Hose (PVC Hose)
- KF 25 + Stainless Steel Bellow (Stainless Steel Hose)
1. Pump Placement
- Choosing the Ideal Location: Your industrial pump performs optimally between 50°F to 70°F. If placing it to the left of your freeze dryer, ensure ample distance for heat dispersion. Alternatively, if your setup includes a spacious table for the freeze dryer, consider situating the pump 6”-8” beneath the machine for a compact arrangement.
2. Demister Installation
- Ball Valve Connection: Securely screw the ball valve onto the demister.
- Demister Attachment: Mount the demister onto the vacuum pump with precision.
3. Connect Hose
- Pump Hose Connection: Firmly attach the hose to the pump.
- Freeze Dryer Hose Connection: Connect the other end of the hose to the freeze dryer.
4. Power Up and Get Going
- Plug It In: Insert the power cord into the back of the machine.
- Switch It On: Engage the power switch (‘line’ symbol for on, ‘circle’ for off). Keep the switch on throughout the freeze-drying process.
- Open Gas Ballast Valve: Rotate the gas ballast valve counterclockwise to its fully open position, maintaining this setting during freeze drying.
5. Post-Batch Demister Oil Drainage
- Remove Demister: Carefully detach the demister from the pump.
- Oil Draining: Open ball valve and empty the oil into an oil filter system.
- Reattach Demister: Secure the demister back onto the pump.
6. Pump Oil Replacement and Filtration
- Timing: Perform this task every 30 batches or after 1000 hours of drying.
- Draining and Filtering Oil: Follow the user manual for oil change instructions. Unlike standard oil pumps, this one lacks a ball valve for oil drainage. Use the provided hex key to gently open the drain screw and let the oil flow out.
- Oil Replacement: Use JB Black Gold Vacuum Pump Oil, Robinair High Vacuum Pump Oil, or any vacuum pump oil with a viscosity of 40-50. Add filtered oil or new oil to the pump.
And that's it! The industrial pump's superior quality, along with its low maintenance, makes a significant improvement in your freeze-drying process.

It is very rare to have oil leak from gas ballast when the DRV10 pump starts ( but it could happen). We recommend customer keeping the gas ballast open during the run to let the moisture out of the pump. But in the rare case that customers find oil leak from the gas ballast, they can open the gas ballast a few minutes after the pump starts running. When the gas ballast is open the pump won’t reach a very very good vacuum, but it is suffice for purpose of freeze drying. Unlike other applications, freeze drying involve a lot of moisture, it is recommended to keep the gas ballast open.
I’m confused. In this article; “Industrial Pump setting up Guide”, it states to “OPEN gas ballast valve and maintaining this setting during freeze drying” … YET, in the ‘Instruction Manual, Two-stage Rotary Vacuum Pumps (DRV10)’; page 13, bottom 2 – “CAUTION” clearly states: “Ensure close the gas ballast port to start operating the pump. The oil might jet out of the gas ballast port during operation around high pressure range” … AND … “Keep gas ballast port closed when not exhausting the condensed gas. If you kept opening the gas ballast port when not exhausting the condensed gas, it might cause the oil splash, power loss or ultimate pressure rise. Also, Opening the gas ballast port will increase the temperature rise, noise level and oil mist volume.”
So, OPEN or CLOSED ‘gas ballast valve/port’ and WHEN it should be open, WHEN should it be closed … and why? Thank you.
From the bottom to the top of the demister is about 18".
What is the total height of this pump with the demister assembled? Needing to determine clearance when placing on shelf underneath the freeze dryer.
