KAP-50 1/2” Pump

The Uniflow KAP-50 1/2” pumps feature an Air
Valve System with Shoe Valve technology.
Multiple suction/discharge ports that provide
several liquid and plumbing options.

Constructed of heavy duty plastic, the center
section resists corrosion from even the most
aggressive chemicals, while providing injection
speed and uniform flow under the most
rigorous environmental conditions.

Fast priming and the industry’s best life cycle
performance will improve your chemical
process with the lowest possible cost of
ownership.

The KAP-50 1/2” size pumps are for the jobs
that require higher flow rates with accuracy
and reliability.

Electronic Pump Controller

Advanced Technology for Controlling and Pumping Industrial Chemicals and Other Liquids

The Liquidtrol Chemical Control System is an advanced controller for the Uniflow Air Operated Double Diaphragm Pump. In combination
with the Uniflow, Liquidtrolʼs cost-e ffective microprocessor electronics initiates, limits, cycles, triggers or regulates pumping activity. Knight
offers three versions depending whether you want to control the pumping activity through a time feed, event feed, or cycle feed.

Pneumatic Pump Activator

Introducing the industries first “out of box” pneumatic air pump switch for manual fluid feed applications.

This manually operated air switch is designed to operate any air operated double-diaphragm pump
up to 1/2” port size or 12 SCFM. The built-in spring return provides “momentary” operation of the
air pump. The pump activator turns the air supply off when the button is not fully depressed. The
pump activator eliminates the worry of employees becoming distracted, leaving their chemical fill
task unmanaged, creating an unsafe environment, or a costly chemical spill. This is the “safe and
full proof” alternative to ball valves and on-off air switches that can be left accidentally running by
operators.

Features and Benefits

• #304 stainless steel case with mounting

• Spring return to off state

• Large palm style button

• Color stickers to identify chemical/fluid color

• Optional pressure regulator mounts on side

• Easy to install/use

Cost effective alternative to timer feed

Great for jug or
bucket fill operations
