DOSING ACCESSORIES
INSTALLATION BRACKETS FOR DOSING PUMPS
This installation bracket, designed and patented by STEIEL, is equipped with a rotating bracket, for wall mounting of PROXIMA PSP series pumps.
The rotating support allows a complete rotation of the pump, in order to facilitate the connection of the dosing pipes and the maintenance interventions on the dosing head.
It is also possible to use it for the horizontal installation, for example on a tank, of wall pumps.
Supplied complete with screws and nuts for mounting the bracket on the wall (or on a tank) and for fixing the pump on the bracket.
- Patented by STEIEL
- Rotatable up to 180° of the swivel mount
- Slots for housing suction and drain pipes
- SMP18 version for wall mounting of PROXIMA PSP pumps
- SMP19 version for installation on wall pump tank
MULTI - FUNCTION VALVES
The multi-function valve is an important accessory, which protects the dosing line from overpressures due to interruptions along the line itself, prevents the siphon effect, helps the pump to prime and serves to vent the dosing line during maintenance.
It is mounted directly on the delivery valve of PROXIMA pumps with standard head, or using a special expansion chamber in the case of heads with self-bleeding option.
Available in different models, characterized by different opening pressures.
- Opening pressure: 6, 10 or 16 bar (depending on model)
- Drain connection for 4×6 mm pipe
- Working temperature: -10 … +45 °C
- Supplied with double seal kit, in FPM and EPDM
FLOW CONTROL SENSORS
“Flow Control” is a flow sensor, designed and patented by STEIEL, which allows precise and reliable monitoring of the passage of the dosing liquid.
It is mounted directly on the delivery side of standard dosing heads or with a special support in the case of heads with self-bleeding option.
It includes a three-wire proximity sensor, which sends the signal to the appropriate digital input of the PROXIMA series dosing pump.
- Different models available, depending on the required capacity
- Internal float anodized in different colors for easy identification of the model
- Operating conditions: temperature 1 … 55 °C, pressure 0.5 … 25 bar, max. density of dosing liquid 1.25 g/cm 3
- Supplied assembled, tested and complete with cable with M8 connector
SIGNAL SPLITTER
This simple device allows you to split a signal from a single sensor into multiple channels.
It can be applied to all devices equipped with a three-wire input, such as the PROXIMA and NOVA series dosing pumps.
- Available with 2 or 4 output channels
- Self-powered version from the first device (10…30V-)
- Version with integrated power supply at 230 V~ 50/60 Hz (other voltages on request)
- IP56 box, for wall installation
LEVEL PROBES WITH FLOAT
The SLP float probes allow you to control the liquid level in the suction tanks, sending an alarm signal, which blocks the dosing when this is missing, and therefore preventing the pump from running empty.
The input to which they are connected must be configured as a normally open contact.
- Model SLP2 with connector for EF110 pumps and EF300 series control units
- Model SLP5 with M8 connector for PROXIMA / NOVA series pumps and EF315 control units
- 2 meter cable
- IP67 protection
SUCTION LANCES
Suction lances are an important accessory for dosing stations, especially where there is an agitator.
They are available in different lengths, for tanks from 25 to 1000 liters, and with different construction features (gaskets, non-return valve ball, level connector, suction tube connection, etc.).
Ring nut available in various colors, to better identify lances combined with different products.

- Connection for 4×6 (standard), 5×8 or 9×12 mm tube
- Bezel color: black (standard), blue, red, yellow
- Max. working temperature 50 °C
INJECTION EXTENSION
The injection extension is a useful accessory for dosing a chemical product directly into the pipe, at a distance from the point of attachment, especially in the case of products such as chlorine-based ones, which tend to crystallize and block the normal injection valves.
It also reduces the risk of corrosion of metal pipes, because the chemical product is injected into the center of the duct.
The STEIEL injection extension is adjustable in depth and extractable, even in the case of pressurized pipes.
- Adjustable insertion depth
- Working conditions: max. temperature 45 °C, max. pressure 6 bar
- PVC body, FPM gaskets
- ½” connections
STATIC MIXERS, MS SERIES
These accessories, mounted along the pipe, exploit the pressure of the liquid flowing in the pipe and allow uniform and homogeneous mixing, which balances differences in concentration, temperature and speed of the fluid.
They are suitable for dosing additives in water treatment, for disinfection (chlorination) of drinking water or for mixing viscous liquids.
They require periodic cleaning, but do not require any replacement.
