Chemical Pump Frequently Asked Questions

A Brief History of the Chemical Industry

Before we start on Chemical Pumps, let's tell you a bit about the history of the chemical industry! This industry has been around for thousands of years, with the industrial revolution leading to a rise in the chemical industry. The year 1740 saw the first sulfuric acid plants being built in Great Britain, with further buildings emerging in France, Russia and Germany over the following 70 years. Moving forward to the 19th Century, the production of synthetic dyes from coal tar became possible, leading to developments in organic chemistry.

However, after World War II, there was a change in industry production, shifting from organic chemicals to petrochemicals, which are from oil or natural gas. Over time, man-made fibres and synthetic fertilisers were introduced and advancements were made in the plastics industry, leading to further progress in the production of organic chemicals from oil and gas, with companies such as BP and Shell producing chemicals from petroleum. Now, there are chemical companies all around the world and the industry is worth billions.

Chemical Pump Frequently Asked Questions

What pump type is best used for pumping Chemicals?

Tapflo would usually recommend a seal less Magnetic Drive Pump or a Solid Block Diaphragm Pump for chemicals.

What is the most important thing to consider when specifying a chemical pump?

Safety of the end user is paramount when selecting a pump for chemicals. If a leak should occur any hazardous chemicals could seriously harm the end user.

What measures can be taken to ensure the end user is safe and the pump doesn’t leak?

Here at Tapflo we have a number of products that we can offer to ensure the product is contained. All of our Plastic Diaphragm Pumps are manufactured from solid block HDPE or PTFE rather than the industry standard and our diaphragms are bonded from 5 pieces of premium material and have a no-nut clean face!Solid Block Plastic Diaphragm Pump

Our Mag Drive Centrifugal Pumps are seal less meaning safe handling of hazardous fluids! If that’s not enough we can also supply barrier protection on all of our Diaphragm Pump range. This means the pump will have an additional set of diaphragms, in the case of a leak the fluid will stay contained in the pump rather than escaping via the air exhaust.

What’s the difference between solid block and moulded?

Great question! Moulding side housing is generally the industry standard within the diaphragm pump sector. This means that the plastic is melted down and poured into a moulding, this can cause stress to the plastic and can destroy some of its original compounds. All of Tapflo's Plastic Diaphragm Pumps are machined from either solid block HDPE or PTFE meaning the original compounds are still intact resulting in a much higher resistance to harsh substances like chemicals.

Chemical Pump Case Study

Tapflo were recently approached by a large chemical manufacturer in the UK and asked to put forward a solution to pump hydrogen peroxide from large IBC’s into smaller containers. The pump they already had was oversized and causing the fluid to froth. The batcher they were using was also batching infrequent amounts and was unreliable.

Application Details:

Fluid: 6% Hydrogen Peroxide

Viscosity: 10cps

Flow Rate: 20-25lpm

Temperature: Ambient

Solids: None

Pipe Work: 1”

Length of discharge: 10m

Suction Condition: 1.2M vertical 3M across

Pumping solution offered:

Pump Type: TK50 PTT Diaphragm Pump with built in Pulsation Dampener

Materials: HDPE and PTFE

Accessories: Tapflo Pneumatic Batch Controller

Connection Size: ½” (1/2” bsp to 1” Tri-clamp adapter supplied at customer’s request)

The pump and batcher were hand delivered within one week of receiving the quotation and was commissioned and installed by one of our team. The pulsation has been significantly reduced meaning the product no longer froths and the batcher is pumping.
