nstall pump that pump-head is lower than the lowest level of pumping fluid. If it is
not , a check valve should be installed. The sucking head of this pump is lower than
100cm and which is no guarantee.
The pressure loss cause by pump pulse should below 1.0 Kgf/cm2, otherwise the pipe
start to vibrate. In this case, a pulse reducer can be installed or reduce piping
length/elbow or increase pipe diameter.
Be aware that pressure discrepancy between input output pipe should higher than the
inner pressure loss of this pump otherwise, overfeeding even siphon phenomenon
may occur. In this case an anti-siphon/backpressure valve(both are optional) should
be installed.
Fluid which is easy to gasify or vaporize(Ex. H2O2, most solvents). Gas in pump
head cause variation of flow rate. In this case purge the gas through drain valve.
Output pipe may install following devices to solve some problems
：
Pulse reducer -To reduce pipe vibration especially pipe is long/thin/plenty of
elbows
Pressure gauge -To monitor output pipe pressure.
Release valve -To prevent pipe from rupture cause by exceptional high pressure
and secure operator against hazard.
Back-pressure -To keep constant pressure of output pipe and improve flow valve
rate stability.
Pipe injector -To connect hose/pipe to other pipe.
Anti-siphon - If pumping destination altitude is lower than source
Valve tank siphon phenomenon occur. In this case an anti-siphon valve
should be installed.

Fixing
：
Fix pump: screws M8(P1.25)-25 *4+ gaskets M8*8+ nuts M8(P1.25)*4 (Standard)
Fix base: foundation screw bolts M8(P1.25)*4 +gaskets M8*4+ nuts M8(P1.25)*4 (optional) or
Expansion screw bolts PF1/8”*4+ gaskets 1/8”*4 + nuts M8(P1.25)*4 (optional) or
Expansion screw bolts PF1/4”*2+ gaskets 1/4”*4 + nuts M8(P1.25)*2 (optional)
