Detailed introduction

The company's 801 product and 1201 product have been applied individually or jointly to more than a dozen quinolone APIs such as ofloxacin, levofloxacin, ciprofloxacin, enrofloxacin and norfloxacin. With the extension of process substitution, follow-up will Apply to more quinolone APIs. In addition to the application of pharmaceutical intermediates, the company also expanded the application of 801 products to the field of pesticide intermediates, and used three major technology platforms to successfully develop new production processes for some pesticide intermediates and new material intermediates, replacing and transforming traditional processes , Began to enter the fields of pesticide fungicides, insecticides, herbicides, photoinitiators of new materials, and pharmaceutical cephalosporins, and the application of products and technology has gradually expanded.

Key words：Pharmaceutical intermediates, pesticide intermediates, new material intermediates

PUMPS INSTALLATION AND APPLICATIONS

These pumps are suitable for clean water without abrasive particles and non-chemical-corrosive fluids. Reliable, compact, economical and simple to use, they are particulary suitable for domestic and industrial applications such as water supply for recirculation in air conditioners and refrigerators, industrial water uses in general, and the automatic distribution of water from surge tanks, watering gardens, lifting water from tanks or wells down to 9m depth. Eguipped with a check valve on the suction side easy no foot valve is required, enclosed environment or sheltered from inclement weather.

PERFORMANCE

• Suction capacity up to 9 meters

PUMP
• Cast iron pump body and support by unigue anti-rust treatment
• Rust-free stainless steel inserts prevent impeller's block when starting after the pump is unused for a long time
• Stainless steel mechanical seal (graphite to ceramic)
• Brass impeller with radial peripheral blades
• Stainless steel shaft
• Self-priming

MOTOR
• C&U bearing
• Copperwinding motor
• Built-in thermal protector for single phase motor
• Insulation class: F
• Protection class: IPX4

OPERATING LIMITS
• Suction lift up to 9m
• Fluid temperature up to 60 ℃
• Maximum ambient temperature 40 ℃
