API 675 Compliant Metering Pump for Industrial Applications

Engineered to meet API 675 standards, this pump ensures high reliability, safety, and performance for critical dosing processes.

High-Capacity Performance (Up to 7000 L/h)

Delivers flow rates up to 3500 L/h (simplex) and 7000 L/h (duplex) at 5 kg/cm²g, making it suitable for large-scale operations.

High-Pressure Capability up to 65 kg/cm²g

Handles demanding conditions with maximum pressure up to 65 kg/cm²g (metallic) and 10 kg/cm²g (plastic), ensuring versatility across applications.

Precision Flow Control with ±1% Accuracy

Offers high dosing accuracy (±1%), repeatability of ±3%, and 0–100% flow adjustment during operation, supported by a lockable micrometer stroke mechanism.

Advanced PTFE-Faced Diaphragm with Safety Monitoring

Features a hydraulically actuated PTFE-faced diaphragm (TFN) for durability and chemical resistance, along with Diaphragm Rupture Detection System (DRDS) for enhanced safety.

Versatile and Robust Fluid Handling Design

Supports viscosity up to 2400 cPs, includes a 10:1 turndown ratio, and offers threaded or flanged connections, ensuring flexibility for various process requirements.
