Industrial pumps

A diaphragm pump is one of the most practical industrial pumps in use today. Typically used as an industrial pump for water transfer for both process and wastewater applications, as chemical pumps, as a metering pump or as a system pressure pump. An air pump or air operated pump has many advantages over standard types of rotating pump technology.

The diaphragm is the motive force rather than a centrifugal rotating impeller, a gear, a lobe or a piston, all of which require specialised seals when used as chemical pumps or slurry pumps.

Diaphragm pumps are ideal air pumps because they are intrinsically safe to use with explosive media like petrol and solvents. The wide range of material options Fluimac diaphragm pumps coffer result in material selections capable of handling almost any chemical. Temperature is also accommodated by the material of construction selections. In South Africa, diaphragm pumps are the first choice of many industries for chemical pumps.

Diaphragm pumping action

The pumping action of an air operated diaphragm pump is uniquely suitable for the transfer of fluids that would normally be a problem for rotary type pump systems. Diaphragm pumps also offer the user simple automation options.

By either closing or opening the fluid side valve, one stops or starts the pump making automation a very easy process. By opening or closing the air feed line one achieves the same pump automation.

Another major advantage of Fluimac air operated diaphragm pumps to the factory owner is the dramatic reduction in damage to pumps from dry running. (Operating a pump without sufficient fluid passing through the pump casing) The downtime and repair costs due to mechanical seal failures is a no show when using diaphragm pumps.

Options to suit your pump application needs

When one needs a pump to transfer fluids, not every application is similar and not every fluid being transferred has the same volatility, pH, or any number of other characteristics. The Fluimac range of diaphragm pumps offers the user a range of materials with which to select the correct pump for the specific application.

Fluimac, Experience the Brand

Fluimac diaphragm pumps compete with every established brand in the air pump industry.
Sandpiper, Wilden, Aro, Blagdon, Yamada and Graco to name a few.
Sandpiper and Wilden are two of the most recognised brands in the air diaphragm pump industry today, due mainly to the length of time these brands have been in the market.
However, as the air diaphragm pump industry has matured, many new designs and companies have entered into this pump supply space.

A passion for helping customers and supplying a unique, reliable and innovative pump system to end users, people have become more and more aware of the outstanding Fluimac advantage.

The exceptional technical design of Fluimac diaphragm pumps with the certified quality of manufacture, coupled with the simple cartridge air motor (Air valve) design which makes repairs and maintenance fast, cost-effective and simple, converts users of older brands to the Fluimac experience.

Fluimac pumps are designed to be repairable with standard tools and relatively unskilled labour. The air valve assembly on most other brands are a complicated mixture of components, “o” rings and slides. The Fluimac diaphragm pumps drive component consists of an air valve cartridge, either repairable by replacing a few “o” rings or simply by replacing the entire component with a cost-effective new cartridge.

Air diaphragm pumps are predominantly used for transferring or pumping fluids that are either toxic, flammable or in other ways a danger to an operator.

Should the air supply be restricted or shut off the pump will stop without damage, this means that by regulating the air supply the operator can control the pump. PLC operation via a solenoid valve on the airline can also mean that this pump is simply and safely able to run on auto. Should the discharge pipe be closed the pump will simply stop, without damage.

This is a huge advantage compared to either positive displacement pumps or centrifugal pumps which would either be damaged or will destroy the pipe systems and seals. It also means that the pump can be controlled by opening or closing the fluid discharge valve. Flow can also be regulated in this way.

Fluimac diaphragm pumps are extremely forgiving when operated by unskilled operators. The Fluimac diaphragm pump is capable of self-priming to a depth of 9 meters at sea level, will achieve discharge heads up to 7,5 Bar and flow rates to 1000 liters per minute.

When used as a water pump the diaphragm pump comes into its own, especially in explosive areas needing to be dewatered. Without the need for dangerous trailing electric cables or expensive certified control switchgear, the pumps are easily deployed to remove flood or wash water from any area. A simple air-line is all that is needed. Fluimac air pumps are often mounted onto trolley bases to facilitate easy mobility inside factories and petroleum refineries.

When it comes to automation for both water pumps and chemical pumps, the Fluimac diaphragm pump range has an ideal pump for all applications. Huge savings can be achieved when comparing other technologies to diaphragm pumps. The reliability of service, low, low downtime and high, high operational efficiency are guaranteed when using diaphragm pumps as dangerous chemical pumps on the plant. The safety aspect coupled with the lack of damage caused by operational challenges when there is a chance of dry running or closed valve operation. These reliability features make Fluimac diaphragm pumps a must have, a direct impact on any industries bottom line, saving on both repairs and downtime.

Consider using a Fluimac diaphragm pump for your application, call our fluid handling experts for help with design and advise on your pump system. With over 40 years of practical pumping experience, we at Fluimac South Africa are certain we will be able to assist you with your diaphragm pump inquiry.

Fluimac South Africa looks forward to assisting you with your selection.

Please consider having the following details available when making your inquiry:-

  1. Fluid?
  2. Air pressure available?
  3. Flow rate required (liter per minute)?
  4. The suction condition, will the pump operate under a flooded suction or will it have a positive suction head?
  5. The temperature of the fluid when pumped?
  6. The viscosity of the fluid when pumped?
  7. A sketch of the proposed installation is always of help.

We look forward to assisting you with your air operated diaphragm pump selection.
