Gear Pumps

Product catalog summary

Overview:
GRI Gear Pumps are primarily designed for metering and transfer applications. They feature a modular design allowing for a wide range of flow rates using standard parts. These pumps are self-priming and maintain a constant flow when RPM and differential pressure are stable. They are constructed with materials that ensure compatibility with various fluids.

Features:

Long life and high pressure capabilities
Reversible and self-priming
Constructed with PPS Polymers for durability
Compact design with excellent chemical compatibility
Positive displacement mechanism

Pump Specifications:

Flow Rates: Up to 2000 ml/min
Max Pressure: 30 psi
Max Fluid Temperature: Up to 180°F (82°C)
Motors: Available in 12VDC and 24VDC, reversible, brush type
Wetted Materials: Body and gears made of PPS Polymer (Ryton®), seals and O-rings of Nitrile, shafts of 630 Stainless Steel, and hose connectors of Nylon

Selection Procedure:
Determine the flow and discharge head requirements for your system. Performance curves are available to match pump models to application needs. Custom OEM options are available for different flows and pressures.

Mesh Size Recommendation:
A minimum 80 mesh screen is recommended for systems free of particulate contamination, while a 400 mesh minimum is suggested for systems with expected particle contamination. Adequate strainer area is necessary to prevent pump starving and cavitation.

Performance:
The document includes a performance chart detailing the total head (PSI) against capacity (ml/min) for various models in the 19000 Series Gear Pump. Each model is specified with motor voltage, type, port positions, connection size, approximate weight, and maximum flow rate.

Typical Dimensions:
Diagrams provide dimensions for different models, indicating inlet and outlet positions for 3/16" ID tubing, ensuring proper installation and compatibility with system requirements.

Gear Pumps Gear Pumps are designed primarily for metering and transfer applications. Their modular design allows a wide variation of flow ranges with a standard parts set. Gear pumps are self-priming and are “constant flow” pumps when RPM and differential pressure are constant. The materials of construction for bodies, gears, and seals provide a wide range of fluid compatibility. Features: • Long life • High pressure • Reversible • Self-priming • Pump assemblies made with PPS Polymers • Compact and durable • Excellent chemical compatibility • Positive displacement 180 Hines Ave. • Bellville, OH 44813 • PH: 419-886-3001 • FAX: 419-886-2338 • www.GRIpumps.com GRI Gear Pump
