NETZSCH Pumps Replacement Parts

NETZSCH is a global specialist in complex fluid management. They have supplied positive displacement pumps worldwide for more than 60 years. NETZSCH pumps are widely applied in the fields of Food/Pharmaceutical, Mining, Chemical, Pulp/Paper, Environment/Energy, Oil/Gas upstream, etc. NETZSCH PC pumps are popular in the market as well as SEEPEX PC pumps and MONO PC pumps.

Among the NETZSCH pumps, their progressing cavity pumps are very popular and used in most countries. During the pumping work, the rotor, stator and some other components would be worn naturally or damaged due to some problems. Then the users need to replace the original spare parts or need some good quality replacement parts instead.

PMV PUMP can supply such high-quality replacement parts for NETZSCH progressing cavity pumps. We can provide the replacement spare parts with complete models, good matching and fast delivery. They are generic parts for NETZSCH PC pumps. The generic parts we supplied for NETZSCH pumps can highly match the original pump parts and be with equivalent service life.

NETZSCH Spare Parts–Replacement Parts

Generally, we supply the whole set of replaceable accessories for NETZSCH processing cavity pumps. The replacement components include the helical rotor, stator, drive shaft, coupling rod, universal joint set and mechanical seal/packing seal. They normally are available in separate parts or a whole set.

Progressing cavity pumps is a member of positive displacement pumps. The pump name explains the pump type and how this type of pumps work. Progressing cavity pumps are also known as Progressive Cavity Pumps, PC Pumps, Cavity Pumps, Progg Pumps, Screw Pumps…

A rotating rotor and a stationary stator are the main components of the progressing cavity pump. The rotor is a helical and round-threaded shaft. It’s running inside and matching with the stator. The stator is a hollow tube and be with an elastic lining inside. Please be aware the pump stator has the same pitch length as the pump rotor. Based on this, it leaves conveying spaces between the hollow stator and the helical rotor. Then the viscous medium can move continuously from the inlet to the outlet side.

Well, when there is a problem with your progressing cavity pump. You need to firstly check what the problem is and which part caused the problem. Normally, you need a professional staff to disassemble, check and replace the damaged parts when the flow rate and pressure decrease, or there is abnormal noise in the pump or the pump fail to rotate, etc. When the damaged part is found, the professional staff would tell you the damaged part number or part name.

When you check the PC pump models, you will find an indication of the pump stage. To know the pump stage quantity, we have some suggestions.

For a screw pump in the off state, a simple way is to calculate the ratio between the length and diameter of the stator. The ratio will give you an indication. Generally, when the ratio is between 2 and 2.5, it’s probably a single-stage PC pump. When the ratio is between 3.5 and 5, it’s probably a two-stage cavity pump.

Of course, some types of PC pumps don’t follow this rule. For example, dosing pumps’ ratios can be somewhat different. And for the extended single-stage pumps, it is only possible to know the stage quantity by disassembling the pump and counting their cavity numbers. Let’s say one stage corresponds to 2 complete sinusoids or 2 cavities (one hollow and one hump).
