Pump Solutions: Diaphragm, Chemical, and Drum Pumps

Industrial Pumps are the beating heart of many industries that require the streamlined movement of liquids in their various processes. The right choice of equipment will ensure the system design flows smoothly. 

The correct selection of industrial pumps will ensure the proper movement and purity of liquids, chemicals, and other fluids that are transferred efficiently and safely. At PumpWorks NZ, we provide surefooted guidance on reliable pumps for industries that demand quality and durability.

In this guide, we’ll explain the different types of pumps we offer and how they can benefit your operations.

Diaphragm Pumps and Pulsation Dampeners

Diaphragm pumps, both Pneumatic and Electric, use hydraulic pressure to move liquids by moving a flexible diaphragm to create suction and discharge. 

These pumps are perfect for moving challenging liquids like corrosive chemicals, abrasive fluids, and high-viscosity fluids. These are extremely versatile, offering solutions where other pumps can’t.

Air-operated double diaphragm pumps can handle sludge, slurry, shear and abrasive liquids. In a manner of speaking, the double diaphragm lets the pump act as the pistons of a gasoline engine to create the desired action.

Unfortunately, these types of pumps deliver a pulsing flow with the stop-start action, where fluids rapidly accelerate and decelerate. This results in fluid pulsations or pressure spikes. 

Surge dampeners can help absorb the energy from these pressure spikes and deliver a more linear flow by accumulating and releasing process fluid when the pump is on its suction stroke. This keeps the fluid in motion, and the dampener helps eliminate vibration and pulsation. 

Diaphragm Pump Characteristics:

• Energy-efficient: Operates using air or hydraulic power, saving electricity.
• Durable: Withstands corrosion and wear, even with tough chemicals.
• Versatile: Suitable for many industries, such as food, oil, gas, and wastewater.

Common uses:

• Chemical processing
• Food and beverage production
• Water treatment

Chemical Pumps

Chemical pumps are required for hazardous or corrosive fluids. These chemical handling pumps are built to handle dangerous substances and harsh environments that would destroy or damage standard pumps. They’re crucial to the oil, manufacturing, pharmaceuticals, and water treatment industries.

The construction of chemical pumps is what makes them different. They’re made from advanced materials like PTFE (Teflon) and TPE (Thermoplastic Elastomer), which resist corrosion, heat, and chemical reactions.

PTPE has broad chemical resistance because of a virtually impregnable shield of fluorine atoms enveloping the carbon structure underneath. It is also perfect for highly aggressive chemicals. TPE is tough yet flexible, so it’s more durable. Its construction also ensures that the pumps require less maintenance and last longer.

Why Are Chemical Pumps Essential?

• Safety: The sealed design of chemical pumps reduces the risk of exposure to hazardous substances.
• Durability: Advanced materials protect against wear and tear, keeping the pump in operation for many years.
• Environmental protection: These leak-proof pumps protect the environment by preventing contaminants from entering the ecosystems they’re in.

Applications of Chemical Pumps:

• Water treatment: Safely transfers chlorine and pH balancers.
• Pharmaceuticals: Handles sensitive chemical solutions.
• Manufacturing: Transfers corrosive liquids like acids and solvents.

Drum Pumps

Transferring liquids from barrels or drums can be messy and time-consuming. Drum pumps solve this dilemma by providing a clean, controlled way to transfer liquids into standard-sized drums, thus reducing spills, leaks, and waste.

Drum pump systems are versatile and can handle many different liquids, from oils and chemicals to food-grade products. They can also handle liquids with varying thicknesses (viscosities), from thin solvents to syrup-like substances.

Drum pumps have options for pneumatic (compressed air-driven) or electric motors, making them suitable for many workplaces. Air-driven motors are typically used in dangerous environments, while electric motor-driven drum pumps fit with all manner of pump tubes outside hazardous areas.

These pumps improve the efficiency of operations and reduce physical strain on workers, making them a must-have for businesses that handle liquids in bulk.

Why Use Drum Pumps?

• Safe and clean: Reduces spills and waste.
• Versatile: Handles oils, chemicals, and food-grade liquids.
• Flexible options: Available with air-driven or electric motors.

Industries That Benefit:

• Food and beverage
• Automotive
• Pharmaceuticals
