Diaphragm Pumps for Furan Resin
Based on the selection requirements for diaphragm pumps for furan resin transportation, considering the media characteristics, process
parameters, and the recommended model J1M-180/0.5, the following provides a detailed analysis of compatibility, technical parameters,
and material selection, along with optimization recommendations:
1. Media Characteristics and Pump Compatibility
Media Solidification Issues
Furan resin will solidify when exposed to air, requiring a pump with strong self-priming capabilities and low residual volume. Diaphragm
pumps achieve leak-free transportation through the reciprocating motion of the diaphragm, effectively reducing media residue and the
risk of solidification. The PTFE diaphragm of the recommended model J1M-180/0.5 is chemically resistant and has a smooth surface, further
minimizing media adhesion.
Viscosity and Flowability
Furan resin has a form similar to gasoline, with a low viscosity and low sensitivity to pump shear forces. Diaphragm pumps are driven by
air pressure or an electric motor, eliminating the need for high-speed rotating parts and avoiding media denaturation due to shear, making
them suitable for transporting low-viscosity fluids.
II. Technical Parameter Compatibility Analysis
Flow Rate and Head
Required flow rate: 1-3 L/min (60-180 L/h). The recommended model J1M-180/0.5 has a maximum flow rate of 180 L/h, fully covering the
required range and enabling precise control by adjusting air pressure or motor frequency.
Outlet head: 1-3 m (approximately 0.01-0.03 MPa). The pump's rated pressure of 0.5 MPa far exceeds the required flow rate, ensuring
stable delivery.
Pressure and Self-Priming Capacity
Inlet Gravity Flow: Diaphragm pumps can self-prime up to a height of 4-8 m (depending on the media density), far exceeding the required
flow rate and eliminating the need for additional priming devices.
Outlet Pressure: The rated pressure of 0.5 MPa can accommodate fluctuations in pipeline resistance and avoid unstable flow due to
insufficient pressure.
III. Material Selection and Durability
Pump Head Material
SS304 stainless steel: Resistant to general chemical corrosion, suitable for non-strong acidic or alkaline media such as furan resin. If the
medium contains chloride ions or is exposed to long-term humidity, upgrading to 316L stainless steel is recommended for enhanced
corrosion resistance.
Diaphragm Material
PTFE (polytetrafluoroethylene): Excellent chemical stability, resistant to furan resin, acids, alkalis, and organic solvents. Its smooth surface
resists adhesion to media, making it suitable for condensate-prone fluids. Ensure the diaphragm thickness (typically 0.5-1.5mm) is sufficient
for frequent start-stop operations.
Seals
If the recommended model does not specify a seal material, fluororubber (FKM) or PTFE-coated rubber is recommended to accommodate
the chemical properties of furan resin.
IV. Motor and Drive Optimization
Motor Power
A 0.55kW motor can meet flow requirements of 180L/h, but ensure frequent starts and stops or long operating times. If the load factor is
below 40%, consider reducing the power to 0.37kW for energy savings.
Protection Rating
IP55 protection provides dust and water resistance, suitable for general industrial environments. If the pump is installed outdoors or in a
humid area, upgrading to IP65 is recommended.
V. Selection Conclusion and Recommendations
Recommended Model Compatibility
The J1M-180/0.5 meets the requirements in terms of flow rate, pressure, and material. The combination of a PTFE diaphragm and SS304
pump head effectively addresses the corrosion and coagulation issues of furan resin.
Optimization Suggestions
Material Upgrade: If the medium contains chloride ions or requires higher corrosion resistance, the pump head can be equipped with 316L
stainless steel.
Seal Enhancement: Specify seal material as FKM or PTFE-coated rubber to extend service life.
Variation Control: Add a frequency converter to precisely adjust flow rate and avoid long-term low-load operation of the motor.
Insulation Measures: Wrap the pump body or pipeline with insulation to slow the coagulation of furan resin in low-temperature
environments.
