Product Introduction
Types & Models
1. Standard G Series (e.g., G20, G30, G50) - General purpose for viscous liquids (oil, sludge, wastewater).
2. High Pressure Models (e.g., GH100, GH200) - Reinforced stators/rotors for pressures up to 48 bar.
3. Corrosion Resistant (e.g., GC Series) - Stainless steel rotors + fluoropolymer stators for chemical/acidic liquids.
4. Food Grade (e.g., GF Series) - FDA-compliant materials for pharmaceutical/food processing.
5. Low Flow Precision (e.g., GM Series) - Miniature designs for dosing/laboratory applications.
Key Performance Features
* Flow range: 0.1-600 m³/h, adjustable via speed control.
* Pressure capacity : Up to 48 bar (high pressure models).
* Viscosity Handling: Ideal for 1-1,000,000 cP (e.g., crude oil, polymers, slurries).
* Efficiency: Constant flow rate, unaffected by pressure changes (95% volumetric efficiency).
* Self-Priming: Handles entrained gases and suction lifts up to 8.5 m.
Material Options
* Rotors: Hardened steel, stainless steel (304/316), or coated alloys.
* Stators: Elastomers (NBR, HNBR, FKM) or PTFE for abrasion/chemical resistance.
Applications
* Oil & Gas: Heavy crude oil transfer, wellhead injection (GH Series).
* Industrial: Wastewater, paint, adhesives (standard G Series).
* Mining: Tailings, abrasive slurries (wear-resistant stators).
Standards: API 11B, ISO 15136-1. G-Series pumps are designed for shear-sensitive, highly viscous, or abrasive media with low pulsation and maintenance requirements.
