1.基本规格
model analysis:
IS: International standard single-stage single- suction centrifugal pump
50: Suction port diameter (50mm)
32: Discharge port diameter (32mm)
125: Impeller nominal diameter (125mm)
Type: Horizontal centrifugal pump (suitable for low viscosity liquid transportation) Flow range: 7.5-15m³/h(adjustable)
Head: 18.5-22m (adjusted according to the impeller cutting situation)
2.结构设计
Pump body material:
Cast iron (standard type) / 304/316L stainless steel(corrosion resistant type) Shaft seal:
Mechanical seal(Si/graphite pairing, leak-proof)
Optional double end seal + flushing water system (suitable for highly corrosive flocculants)
Impeller: Closed impeller (anti-clogging design)
Optional PP/PVDFmaterial (chemical corrosion resistant)
3.Power and performance
Motor power: 2.2kW (380V/50Hz, variable frequency control available)
Speed: 2900r/min (standard) /1450r/min (low shear option)
Applicable media:
polyacrylamide (PAM), PAC and other flocculant solutions
Viscosity range: ≤500cP (high viscosity requires special design)
Working temperature: ≤80℃ (high temperature type can reach 120℃)
4. Flocculant transfer adaptability
Anti-shear design: low-speed impeller (reduce polymer chain breakage) Anti-crystallization measures:
Optional insulation jacket (maintain solution temperature)
Quick-disassembly structure (easy to clean residual flocculants)
5.设备尺寸和重量
Overall dimensions: ≈600×400×500mm (length×width×height)
Machine weight:80-120kg (depending on the material)
遴选建议
1. Corrosive flocculants (such as solutions containing Cl): Select 316L stainless steel or fluorine-lined pump body.
2.High-concentration PAM solution: It is recommended to configure a low-speed motor (1450r/min) to reduce degradation.
3.Maintenance points: The pump chamber must be flushed immediately after shutdown to prevent the flocculant from solidifying. If a corrosion resistance test report or customized solution is required, please specify the specific medium composition (such as pH value, solid content, etc.).
