Keep Your NACHI PVD Pumps Running Smoothly – Avoid Costly Failures!

NACHI PVD pumps are renowned for their durability and high performance, but like all hydraulic systems, they are sensitive to maintenance and operating conditions.

-Based on real-world experience, the most common issues include:

1️⃣ Oil Contamination (Most Frequent – 70% of Cases)

Symptoms: Cylinder block scratches, piston wear, valve plate burn, shoe detachment

Causes: Dirty oil (metal debris or dust), clogged filters, uncleaned systems

Effect: Internal components are often severely damaged, while the shaft may remain intact

2️⃣ Oil Starvation / Air Ingress

Symptoms: Pump noise (squealing), burned valve plate, darkened cylinder block, damaged shoes

Causes: Leaking suction lines, low oil level, overly viscous oil

Effect: Internal parts can fail, but the main shaft often survives

3️⃣ Overheating / Overload

Symptoms: Oil turns dark, internal components fused, a clear increase in clearances

Causes: Continuous heavy-duty operation, tough environments like rock excavation or mining

Effect: Rapid wear of pump internals

4️⃣ Regulator Malfunction (Easily Overlooked)

Symptoms: Constant high pressure, system blockage

Effect: Can “destroy” the pump if not addressed in time

Solution: Preventive maintenance and timely replacement of worn components can save thousands in downtime and repair costs.
