positive displacement pump manufacturers: When you need consistent, reliable fluid flow, nothing beats a positive displacement (PD) pump. From chemical dosing to heavy slurry handling, these pumps deliver precision performance under pressure. But choosing the right positive displacement pump manufacturer makes all the difference.

Here’s why industries across Australia turn to trusted suppliers like MultiTorque for dependable PD pump solutions—and how to ensure you’re getting the best.

What Is a Positive Displacement Pump?

Unlike centrifugal pumps that rely on impellers, positive displacement pumps move fluid by trapping a fixed amount and forcing (displacing) it into the discharge pipe. This makes them ideal for viscous, abrasive, or chemically aggressive fluids.

There are two main categories:

• Rotary PD pumps (gear, screw, vane, lobe)

• Reciprocating PD pumps (piston, diaphragm, plunger)

---

1. Flow Rate That Doesn’t Flinch

Need precise volume regardless of system pressure? Positive displacement pumps offer constant flow, unaffected by discharge pressure changes. This makes them perfect for:

• Chemical injection systems

• Metered dosing

• Hydraulic power units

This level of control is critical for sectors like pharmaceuticals, water treatment, oil & gas, and mining.

---

2. Superior Viscosity Handling

High-viscosity fluids like molasses, sludge, or industrial grease are no problem for PD pumps. Their design prevents slippage and keeps flow rates consistent—even with fluids that would choke a centrifugal pump.

---

3. Self-Priming and Dry Run Capable

PD pumps excel in challenging setups. Most are self-priming and can handle intermittent dry running without damage—an essential feature for remote industrial sites or start-stop systems.

---

4. Built to Withstand the Harshest Conditions

The best positive displacement pump manufacturers use robust materials like stainless steel, cast iron, and high-performance elastomers. These pumps are built to resist:

• Abrasion from solids

• Chemical corrosion

• High-pressure operation (up to 1000+ PSI)

This ensures long service life, even in tough mining, chemical, or wastewater environments.

---

5. Low Maintenance, High Longevity

With fewer moving parts and minimal shear on fluids, PD pumps offer lower maintenance demands and longer uptime. They’re ideal for 24/7 operations with minimal intervention, reducing your total cost of ownership.
