How They Work
Venturi pumps are commonly used for coolant mixers. The moving water across the orifice creates a vacuum, drawing coolant into the water stream. The combination of the two laminar flows creates a turbulent zone thoroughly mixing the two fluids.
Since there are no moving parts, the pump has a high degree of reliability. The needle valve allows for great precision in setting the proportion of coolant mixed with water.
Machinist Mixer Troubleshooting Tips
Low Concentrations or None at All
- Check the discharge hose. If you are NOT using the hose we provided, make sure you are using NO
MORE than 40” of discharge hose, with a minimum UNINTERRUPTED ID of 1/2” for 3 gpm models,
and 3/4” for 10 gpm models. Make sure that the hose has no kinks or other obstructions. If delivering
mix through a garden hose, for instance, a proportioning pump is required.
- Examine the check valve at the bottom of the standpipe. Debris can keep it open, allowing concentrate
to drain back into the drum. The check ball should be below the valve’s set screw.
- Check the water pressure. Our equipment requires a minimum pressure of 25 psi. TEST: Using the mixer
with needle valve closed, fill a pail of known volume and time it. If you can fill a 1 gallon pail in 20
seconds there is enough pressure for our 3 gpm unit. If you can fill a 1 gallon pail in 6 seconds there is
enough pressure for our 10 gpm unit.
- The needle-valve (dial) is numbered as a guide only. It does not indicate proportions. Turning the dial
clockwise reduces coolant concentrate ratio.
- Check the coolant concentrate level in the drum. You may be running out.
- Check the viscosity of the coolant concentrate. Our equipment is designed for up to 500 SUS at 100° F.
(SUS=saybolt universal seconds). 500 SUS is about the same as SAE30 motor oil.
Water Draining into Concentrate Container
- Shut water ball valve off (check valve on end of standpipe is not rated to hold fluid under pressure).
- Check water ball valve for cracks or damage.
- If using a solenoid valve, install it on inlet before water supply (check valve on end of standpipe is not
rated to hold fluid under pressure).
Concentrate Siphoning from Container
- Remove discharge hose from output holding container or sump.
- Verify concentrate container’s breather hole is open.
- Verify that the check valve is free of debris.
Lifetime warranty on all parts.
- Any use of this product outside the suggested parameters will void all warranties.
