Common features for every model

Solenoid dosing pumps

The SDP family provide an alternative solution in lower rates application field where end users look forward reliable results and simple operation.

Using a built-in microprocessor, with its own flexibility, makes the SDP series extremely complete and suitable for a wide range of applications, thanks to several functions included in the same pump, even with few models.

All chemical dosing pumps are complete of accessories to improve the operation and accuracy of the chemical dosing pump:

• Injection valve
• 1.5 mt suction pipe;
• 1.5 mt delivery pipe
• Strainer

Fittings:

• Polyethylene tanks
• Relief valves and back pressure valves
• Safety relief valve
• Injection valve
• Foot valve
• Pulsation dampeners
• Calibration pot

Positive displacement sandwich hydraulic diaphragm dosing pump

Positive displacement plunger dosing pump

„SDI” Series - Sandwich Hydraulic diaphragm dosing pumps comply with mechanical and performance API 675 standards. Furthermore they comply with ATEX standard, therefore they can be installed in hazardous area.

Mechanism is an internal worm gear, fully oil bath lubricated with possibility to be coupled with others independently from the size and stroke number to obtain multi-heads unit.

Stroke adjustment can be carried with the pump at rest or in operation and it can be manual or automatic through automatic actuator driven by 4-20 mA; different BUS; pneumatic.

Accuracy within ± 1% within 10-100% of rated capacity.

A built-in safety valve is installed in the hydraulic circuit, in order to protect the diaphragm against over pressure. The peculiarity of this pump is the special sandwich diaphragm and the reliability of the diaphragm rupture detection system.

Fittings:

• Relief valves and back pressure valves
• Safety relief valve
• Injection valve
• Foot valve
• Pulsation dampeners
• Calibration pot

Note: higher pressure are available
