DOSING PUM P ACCESSORIES
QUICK REMOVABLE INJECTION LANCE
QUICK REMOVABLE INJECTION LANCE guarantees
clean and fast maintenance operations of the injection no-
return valve. Furthermore allows the operator to adjust
the length of the injection point inside the pipe of the
sy stem to treat thus set the injection point at the center of
the pipe where the internal flow will guarantee better
mixing. Removable injection lances are in PVC or PVDF
INJ ECTION LANCES
INJECTION LANCE allows the operator to adjust set
the injection point at the center of the pipe where the
internal flow will guarantee better mixing and
homogeneous dosing.
a - Polyethylene discharge hose
b - Injection fitting with no-return valve
c - Injection lance
d - 3/8" female steel gas thread connector
e - Process plant pipe
f
- Injection point
Injection lances are in PP, PVC or PVDF
RELIEF VALVE or BACK-PRESSURE VALVE
This valve can be utilized either as:
RELIEF VALVE: opens an overflow line if the preset
pressure limit is exceeded. This application also i s a
safety device to protect pump diaphragm.
BACK-PRESSURE VALVE: useful when injection
point is below dosing tank to prevent siphoning
effect.
Configurations PVC-FPM / PVC EPDM / PVDF
PULSATION DAMPNER
Pulsation dampeners are used to smooth pulsations
injections in the process plant pipe generating a
continuous small flow
This application allows limits pressure loss along the
pipelines and prevents interfering vibrations.
Configurations 3/8” PVC-FPM / PVC EPDM
ANTI-SYPHON VALVE THREE FUNCTIONS VALVE
Useful when injection point
is below dosing tank to
prevent siphoning effect.
Max back pressure 2 bar.
Available with EPDM valve
upon request Useful for 20 l/h pump head type
with no build-in air bleed PP
material, 3 functions are:
• air bleed
• back pressure (1bar)
• antisyphon
AVAILABLE DOUBLE THREAD NIPPLES AND REDUCTION FITTINGS
