1.
Tubing
Connections
The MicroTron™ pump uses carefully matched components to achieve a predictable metering
output. This predictability can only be maintained if all fitting sizes remain unaltered.
Do not
attempt
to reduce tubing size. All tubing connections should be double checked to insure against leakage.
If hazardous chemicals are being pumped, use shielding around discharge tubing.
NOTE: When cutting lengths of tubing for your installation, ensure a clean, square
cut. Use short lengths of tubing and as few connections as possible.
Do not overtighten the tubing connectors. Tighten the fittings no more than 1/4 turn after the
fitting contacts the seal. Hand tighten only.
Do not use a wrench or pliers
as they may damage
the fittings. Do not use Teflon tape except on NPT fittings.
Be sure to observe applicable local
plumbing codes.
WARNING:
Clear flexible tubing is not intended for pressurized use.
2. Suction Lift vs Flooded Suction Applications
Suction Lift Installation
Mount the MicroTron™ pump on the top of a molded tank, not to exceed 5 feet from pump to
bottom of tank.
Flooded Suction
This installation is recommended for very low outputs, solutions that off-gas and high viscosity
solutions. Priming is easier and loss of prime is reduced.
