1.0 Introduction
Congratulations on purchasing the Flex-Pro variable speed Peristaltic Metering Pump.
Your Flex-Pro pump is pre-configured for the tubing that shipped with your metering pump. The tubing assembly
has an Identification number printed for easy re-order.
Please Note: Your new pump has been pressure tested at the factory with clean water before shipping. You may
notice trace amounts of clean water in the pre-installed tube assembly. This is part of our stringent quality assur-
ance program at Blue-White Industries.

! The Flex-Pro Pump’s motor speed is linear over the entire 0.05% to 100% adjustment range.
! Output versus pressure is nearly linear in all models. Larger tubes exhibit greater losses.
! See the instruction manual for output versus viscosity curves.
! For optimum tube life, specify the pump to operate at the lowest possible RPM and pressure.
! Output based on testing with water at 72 F, 5 foot suction lift, atmospheric conditions at sea level.
* Inlet/outlet connection type
S = 3/8” OD x 1/4” ID tubing compression type connections (A3 models only)
M = 1/2”male NPT (available on A3 & A4 models)
