Knight Equipment KP1H LP User Manual

Chemical Dispensing Systems
for Low Water Pressure

The KP1H LP is our newest expansion of our proven KP1H platform, which allows for
consistent and accurate proportioning in facilities and buildings with low water pressure.
With the KP1H LP, both bucket fill and bottle fill can efficiently dispense chemical at
1 GPM (3.6 LPM) in water pressure as low as 12.5 PSI (.86 bar).

KP1H LP and Low Water Pressure

Often, low water pressure is a common uncontrollable problem in many facilities and
buildings. This creates a problem for many proportioners where a minimal of 25 PSI (1.72

ar) of water flow pressure is needed to operate properly. At low water pressures, the

b
flow of water through the most dispensers will not create enough suction to draw the
correct amount of chemical into the water stream, resulting in low chemical/water ratios.
This diluted chemical can create cleansers with insufficient cleaning power, or when using
sanitizers or disinfectants, incorrect dilutions could result in a non-compliance with health
department or other regulatory bodies. The design of the KP1H LP proportioners ensures

hat target dilution ratios are achieved every time at water pressures as low as 12.5 PSI

t
(.86 bar). The KP1H LP & KP1H Complete will dispense accurate dilutions with bucket fill
and bottle fill at a 1GPM (3.8 LPM) flow rate.
