AR70BP LOW-PRESSURE DIAPHRAGM PUMP, 74 L/MIN

The AR70BP C low-pressure diaphragm pump is a dual-diaphragm pump designed with external ports and a 1 3/8" non-through shaft. It is rated for a flow rate of 74 l/min and a pressure of 20 Bar. These specifications allow for precise identification of the part number when replacing or overhauling the pump assembly.

A dual-diaphragm pump for a specific application

This part number belongs to the family of low-pressure diaphragm pumps, used when a pump suitable for a mechanically driven liquid circuit is required. For this version, identification is based primarily on its dual-diaphragm design.

The designation AR70BP C is a direct identifier for finding the correct pump. With this type of component, it is important not to rely solely on visual appearance: the port configuration, shaft type, and flow rate and pressure values are among the truly useful selection criteria.

Key Characteristics for Identification

This pump has the following characteristics:

• Designation: AR70BP C
• Type: 2-diaphragm pump
• Ports: external
• Shaft: 1 3/8" non-through
• Flow rate: 74 l/min
• Pressure: 20 bar
• Material: plastic-coated aluminum

All of these features help distinguish this pump from similar models. The plastic-coated aluminum material is also a defining characteristic of the model as described here.

Why the Shaft and Port Configuration Are Critical

When choosing a replacement pump, the shaft type and port configuration are often the first things to check. Here, the shaft is specified as 1"3/8 non-through. This specification directly affects compatibility with your existing setup and compatibility with the intended drive.

The presenceof external ports is another key identifier. It allows you to compare the layout of your current pump with this version, to avoid any differences in installation or connection during the replacement.

Useful Guidelines Before Ordering

To select this low-pressure diaphragm pump correctly, first compare the model number AR70BP C with the dimensional or functional specifications explicitly known for your existing system: number of diaphragms, 1"3/8 non-through shaft, external ports, flow rate of 74 l/min, and pressure of 20 bar.

If your current pump has a different shaft configuration, port placement, or specifications, it’s best to verify compatibility before replacement. To ensure a smooth return to service, rely primarily on technical identification details rather than mere visual similarity.

If in doubt, refer to the complete model designation and specifications for this version to confirm that you are ordering the correct pump.

FAQ — Frequently Asked Questions

What does the model designation AR70BP C refer to?

The designation AR70BP C identifies a low-pressure diaphragm pump with two diaphragms. To identify it, also compare the features associated with this version: external ports, a 1"3/8 non-through shaft, a flow rate of 74 l/min, and a pressure of 20 bar.

How can I verify that this pump is a direct replacement for the one already installed?

First, check the identification and configuration. Verify the model designation AR70BP C, the number of diaphragms, the 1"3/8 non-through shaft type, the presence of external ports, and the specified values of 74 l/min and 20 bar.

What does “1"3/8 non-through shaft” mean?

This refers to a 1"3/8 drive shaft in a so-called non-through configuration. This is important when replacing the pump, as the drive configuration and shaft-side dimensions must match your existing installation.

Is this pump a low-pressure version?

Yes, this part number is indeed a low-pressure diaphragm pump. It is rated for a pressure of 20 bar and a flow rate of 74 l/min, which makes it a useful identifier to distinguish this version from other pumps in the same product family.
