DP Series Explosion-proof Dual-Plunger High-Pressure Pump
DP Series Explosion-proof Dual-Plunger High-Pressure Pump
DP Series Explosion-proof Dual-Plunger High-Pressure Pump
The DP Series Explosion-proof Dual-plunger High-pressure Pump carries an explosion protection rating of Exd IIB T4. It adopts self-developed cold-pressed plunger rod assembly technology to achieve coaxiality below 0.01 mm, ensuring long-term stable operation of the pump.Multi-phase cam technology downsizes the pump body and reduces fluid delivery pulsation, further improving feeding stability. The multi-functional software controller supports constant-pressure feeding mode and gradient feeding mode.To accommodate diverse sample transfer characteristics and different feed flow rates, nearly 30 pump variants with diverse flow ranges and wetted materials including 316L stainless steel, Hastelloy and PTFE are available for selection.
Features
-
To accommodate the need for feeding diverse raw materials with varying properties, options like 316L stainless steel, C276 alloy, and PTFE are offered.
-
A flow rate range of 0.001-3000 mL/min is available to ensure an optimal flow range.
-
An open control platform is provided, featuring multiple communication ports, including RS485 and RS232.
-
Users can freely switch between two working modes: constant current mode and constant pressure mode.
