Product Introduction

The CYF series hydrochloric acid centrifugal pumps (referred to as the hydrochloric acid pump) are strictly designed in compliance with ISO international standards. Featuring integrated non-metallic materials and fluid structures, they are suitable for long-term transportation of acids, alkalis, hydrogen peroxide, and other highly corrosive media (free of solid particles) at any concentration under operating conditions ranging from -85°C to 200°C. These pumps exhibit strong corrosion resistance, anti-aging properties, and chemical stability, while their non-toxic, non-degradable materials ensure the purity of the transported media.

This pump model features high energy efficiency, a wide flow and head range, compact structure, and easy maintenance. Its excellent overall sealing performance completely eliminates the common leakage issues found in traditional pumps and valves.

Parts

• Pump Casing: The outer shell of the pump. Typically constructed from materials such as polyvinylidene fluoride (PVDF), polypropylene (PP), fluoroplastic alloy (F46), or reinforced polypropylene, it exhibits exceptional corrosion resistance against highly corrosive media like hydrochloric acid.
• Impeller: The core rotating component of the pump. Matched to the pump casing material, it is commonly made of PVDF or CFR-PP (carbon fiber reinforced polypropylene), offering strong corrosion resistance.
• Coverplate / Rear Cover: Used to seal the pump casing and support the mechanical seal or bearing assembly, facilitating maintenance.
• Mechanical Seal: Provides dynamic sealing between the rotating pump shaft and stationary coverplate to prevent fluid leakage, serving as a critical component in centrifugal pumps. Core components—the stationary ring and rotating ring—are often coated with silicon carbide (SiC), aluminum oxide ceramic, or polytetrafluoroethylene (PTFE). Elastic elements like O-rings typically use fluorocarbon rubber (FKM) or PTFE to extend seal life in hydrochloric acid environments.
• Shaft: Connects the motor to the impeller, transmitting torque. Typically made of stainless steel with PTFE (polytetrafluoroethylene), ceramic, or plastic material matching the pump body for corrosion resistance against hydrochloric acid.
• Bearing Bracket: Supports the pump shaft and rotor components.
• Coupling: Connects the pump shaft to the motor shaft, transmitting power.

Features

• Standardized design: The hydrochloric acid centrifugal pump is designed and manufactured in accordance with international standards and in combination with relevant national standards. Its performance, rated performance point and size are equivalent to the international standard ISO2858.

• Patented lining process: The pump body and pump cover are both made of metal (HT200) matrix lined with fluoroplastic, and the impeller is made of metal insert (WCB) and fluoroplastic alloy pressed and molded. Advantages: wide range of corrosion resistance, high strength and durability.

• Two sealing structures: This series of pumps adopts two sealing methods: single-end mechanical seal and double-end mechanical seal, which can be selected according to specific working conditions.

Application

The chemical centrifugal pump for hydrochloric acid transfer is a high-performance corrosion-resistant pump made of plastic alloy, developed through specialized processes and innovative design. Featuring a compact structure, smooth operation, easy maintenance, and energy efficiency, it is the ideal equipment for transferring highly corrosive media. This pump is specifically designed for conveying various corrosive liquids, primarily including:

• Acidic media: such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, hydrofluoric acid, etc.;
• Oxidizing agents: sodium hypochlorite, hydrogen peroxide, bromine water, etc.;
• Other corrosive chemical media: alkali solutions, organic acids, solvents, corrosive reagents, etc.

⚠️ Precautions: Strictly prohibited from conveying media prone to rapid crystallization or containing large amounts of hard particles. If conveying materials with a small amount of particles is necessary, a wear-resistant mechanical seal must be selected and the operating conditions must be specified in advance.
