How to Select the Best Corrosive Chemical Transfer Pump for Your Application

You’re likely to find a corrosive chemical transfer pump in virtually every manufacturing operation. Their purpose is to safely transfer chemicals from one container to another. They are designed to resist abrasive liquids and deliver reliable, efficient chemical transfers. Today, these pumps are vital in applications for various industries.

A corrosive chemical transfer pump can be used in multiple applications including the following:

  • Chemical Manufacturing/Distribution
  • Water/Waste Water Treatment
  • Aquarium/Aquatic Life
  • Diesel Exhaust Fluid
  • Power Plants
  • Agriculture
  • Electroplating & Anodizing
  • Printed Circuit Boards & Electronics
  • Bio-Filtration and Odor Control
  • Mining
  • Pulp & Paper
  • Steel Processing
  • Bio Fuels

Key Questions to Ask for Corrosive Chemical Transfer Pump Selection

Each industry and application pose unique challenges and requirements. To choose the best corrosive chemical transfer pump for the job, consider the following questions.

What are the fluid characteristics?

Consider what type of fluid will be transferred using the corrosive chemical transfer pump. The characteristics of the fluid will determine which pump is suitable to complete the transfer. Important characteristics include:

  • Concentration
  • Temperature
  • Specific Gravity
  • Viscosity
  • Flammability
  • Combustibility
  • Corrosiveness

What are the application characteristics?

Next, consider the specific application for which the corrosive chemical transfer pump will be used. What are the setting conditions? What are the operation parameters?

Key considerations include:

  • What is the required flow rate?
  • What is the total head or pressure required?
  • What type of containers are involved?
  • What type of transfer is needed? (rail car to truck, bulk to storage, etc.)
  • Where is the liquid located in reference to the pump?
  • How long will the pump need to operate?
  • Will the pump be indoors or outdoors?
  • What is the altitude?

What are my options?

Once you’ve defined the fluid and application characteristics, the next step is to review the options for your application. Several pump technologies are available. Typically, one style is more suitable than the others for a specific operation:

  • Drum/Barrel pumps: These pumps are designed for transferring corrosive chemicals from and between drums, totes, pails, and other containers. 
  • Centrifugal Pumps: This pump style can be mechanically sealed or sealless (magnetically coupled). These pumps are available in a wide range of materials and offer a broad range of flows and head capabilities.
  • Air Operated Double Diaphragm Pumps (AODD): With simple construction, these pumps typically operate with compressed air. They are suitable for viscous fluids and highly abrasive slurries.

What construction material is suitable for the application?

A corrosive chemical transfer pump can be made from several durable materials. However, the characteristics of the fluid and application will determine which material is best for your operations. Three materials are commonly featured in the construction of corrosive chemical transfer pumps.

Polypropylene: This material is a crystalline thermoplastic. It is made from propylene monomers. As a synthetic resin, it offers flexibility, durability, and chemical resistance.

PVDF: Polyvinylidene Fluoride is a highly inert thermoplastic. Its stability and other properties make it resistant to wear and extremely strong and durable.

Stainless steel: This steel alloy contains at least 10% chromium. Its construction makes it corrosion resistant. One of the most commonly used stainless steel grades for corrosive chemical transfer pumps is 316 stainless steel. This grade is composed of a small percentage of carbon, 2-3% molybdenum, 10-14% nickel, and 16-18% chromium. This combination makes the steel more corrosion-resistant.
