Hydraulic diaphragm pumps are manufactured in accordance with API 675 standard.
SDI series pumps are suitable for use in cases where:
- the dosing liquid contains small amounts of suspended solids;
- the dosing liquid is toxic;
- liquid leakage is unacceptable.
A built-in safety valve is installed in the hydraulic pressure circuit.
A special feature of this pump is a special three-layer membrane and a reliable membrane rupture detection system.
Accuracy is than 1% from 10 to 100% of maximum performance.
Max. performance: 400 (SD 175); 1564 (SD 250); 4028 (SD 350); 247 (AP SD 175); 711 (AP SD 250); 1496 (AP SD 350).
Max. pressure: 14 (SD 175); 14 (SD 250); 14 (SD 350); 40 (AP SD 175); 80 (AP SD 250); 56 (AP SD 350).
