APS41 COMET-TYPE HIGH-PRESSURE DIAPHRAGM PUMP

The APS41 high-pressure diaphragm pump is a sprayer pump designed to pressurize the system. This model is identified by its 3-diaphragm configuration, its solid shaft with 6 holes, its flow rate of 38 l/min at 540 rpm, and its pressure of 40 bar. These specifications are the first points to check when replacing a pump already installed on your machine.

Role of this pump in a sprayer

A diaphragm pump supplies liquid to the spray system and helps maintain the operating pressure required by the system. Within this product family, precise model identification is essential, as several pumps may look similar but have different specifications.

The APS41 model is designed for high-pressure applications. The 40 bar rating is therefore an important factor if your sprayer requires sustained high pressure. For a proper replacement, this specification must be matched to your sprayer’s actual requirements.

Useful Features for Identifying the APS41

The first distinguishing feature is the presence of three diaphragms. This detail helps differentiate this pump from other similar versions. The second key identifying feature isthe solid shaft with six holes; check this directly on your current pump to verify that the mounting configuration matches.

• Type: High-pressure diaphragm pump
• Model: APS41
• Number of diaphragms: 3
• Shaft: 6-hole solid shaft
• Flow rate at 540 rpm: 38 l/min
• Pressure: 40 bar

The flow rate of 38 L/min at 540 rpm completes the identification. This specification links the pump to a specific drive speed and provides a concrete reference for comparing it to your existing equipment.

How to Verify the Correct Part Number Before Replacement

Before ordering a sprayer pump, note the identification marked on the unit installed on the machine and compare it with the visible specifications of this APS41. Two high-pressure pumps may look similar overall but differ in their shaft, flow rate, or pressure.

For this part number, the combination of APS41 + 3 diaphragms + non-through 6-hole shaft is particularly useful. The combination of 38 l/min at 540 rpm and 40 bar then allows you to narrow down your choice based on your system’s requirements. If your sprayer already uses this model number or an identical configuration, here are the key criteria to verify.

A clear basis for comparing your current pump

This pump is suitable if you are looking for an APS41 with the specifications described above. In the absence of a detailed machine list, the safest method is to check the part number on the pump, the shaft configuration, and the flow rate and pressure values. If these details match your setup, you have a reliable basis for confirming your selection.

FAQ — Frequently Asked Questions

What does the flow rate of 38 L/min at 540 rpm correspond to?

This is the volume of fluid delivered by the pump when its drive rotates at 540 rpm. This value is used to compare your current pump with the APS41 model. If the drive speed of your system differs, the flow rate may vary depending on operating conditions.

What does “6-hole non-through shaft” mean on this APS41 pump?

This refers to the configuration of the shaft and its mechanical connection, in this case a 6-hole mounting. This is an important identifier for selecting the correct pump, as this drive configuration must match your existing setup on the sprayer.

Can the APS41 model replace any sprayer pump?

No, you must compare several criteria before replacing it. At a minimum, verify the APS41 part number, the presence of 3 diaphragms, the 6-hole non-through shaft, the flow rate of 38 l/min at 540 rpm, and the pressure of 40 bar as measured on your current pump.

Why is the number of diaphragms (3) useful for identifying this pump?

The number of diaphragms helps distinguish this pump from other similar models. Within a family of high-pressure pumps, a part number may vary depending on its internal configuration and flow rate. Identifying three diaphragms therefore helps narrow down the identification based on the shaft and operating parameters.
