High-Pressure Dosing Diaphragm Pump
Tapflo Gulf is proud to be the exclusive UAE Partner of Doseuro, a leading Italian manufacturer of the highest-quality Metering Pump Solutions.
Our High-Pressure Dosing Diaphragm Pump is constructed for precision and reliability in the most demanding applications. These pumps are designed to handle liquids containing small amounts of suspended solid particles, and are perfect for dosing toxic, corrosive, and hazardous mediums where leakages are not permitted. Equipped with a diaphragm rupture detector and built to operate under high pressure, these pumps meet the stringent requirements of various industrial applications.
Typical applications for our High-Pressure Dosing Diaphragm Pump:
- Oil & Gas
- Chemical Processing
- Pharmaceutical
- Power Generation
- Petrochemical
- Pulp & Paper
Overview
Our High-Pressure Dosing Diaphragm Pump complies with API 675 and ATEX standards, ensuring high performance and safety in hazardous areas. Featuring an internal worm gear mechanism, fully lubricated in an oil bath, these pumps can be coupled with other units for multi-head configurations. Stroke adjustment can be performed manually or automatically, even during operation. The pumps maintain an accuracy of ±1% across 10-100% of their rated capacity. They include mechanical replenishment and an internal safety system to protect against overpressure and suction line obstruction.
