MPP 70-35 - 401007

Variant:

Fully automatic test pump for carrying out water pressure tests, e.g. according to DVGW W 400-2, ÖVGW W 101, EN 805 - max. outlet pressure 35 bar - delivery volume 70 l/min. - Voltage 400 volt - 50 Hz - Power consumption 5.5 kW - Test pressure adjustable in 0.1 bar steps - Frequency converter and speed control for adapted pressure build-up and pressure maintenance without pressure surges - freely adjustable, constant speed via "manual operation - check valve for locking the pressure line - Storz connection and quick couplings for water inlet and water outlet - optionally with flow measurement (necessary for air volume determination in smart memo) - optional with disinfection procedure for MPP - optional with wheel set Suitable for pressure build-up in large pipeline volumes. For small pipeline volumes with V < 1m^3, the MPP 70-35 is only suitable to a limited extent, as the test pressure may be "overrun".

Description

Pressure tests are a recognised method for inspecting the pipeline system. For drinking water distribution, the DVGW specifies the technical rules in Code of Practice W 400-2. This states that each pipeline must be subjected to a pressure test after installation in order to "determine the proper execution of the installation of the pipes [...] as well as the tightness of the pipeline as a whole." For larger pipeline volumes, motorized pumps must be used to build up the pressure in the pipeline within a required period of time.

Advantages

test pressure adjustable in 0.1 bar steps
frequency converter for adapted pressure build-up and pressure maintenance without pressure surges
Storz coupling and quick couplings for water inlet and water outlet
optionally with wheels
optional with flow measurement
optional with disinfection procedure

Features MPP 70-35

Enables pressure build-up for all procedures according to W 400-2

Robust stainless steel frame, smart design combined with consistent Esders quality

Max. flow rate 70 l/min at outlet pressure of 35 bar

Automatic re-pumping and pressure control via integrated control circuit

Non-return valve for locking the pressure line and integrated overpressure protection

Can be combined with smart memo

Combination with smart memo

With our smart memo pressure test case, menu-guided test sequences of various types can be carried out, saving time and avoiding incorrect performance of a test. With the DVGW W 400-2 option package, the smart memo receives all current pressure test procedures according to W 400-2, including extensive documentation options and digital measurement data management via Esders Connect. This makes your everyday work easier.

Our new MPP 70-35, like the MPP 30-30, is also "smart" and can communicate and share data with our smart memo via a wired interface. Through the communication of both devices, the smart memo can remotely control the MPP 70-35 during an ongoing test. This further automates the test procedure for you and prevents incorrect operation or incorrect execution of the procedure.

Air volume determination and remote control*

for water tests

The smart memo and the MPP 70-35 are the devices used for water pressure tests. Through their wired interface, they can communicate with each other and exchange data. This interaction offers various advantages and additional functions, including air volume determination and remote control. Simply start the test on the device and the smart memo performs almost all steps of the test automatically.

Advantages

Saves time if there is too much residual air in the pipe: you do not have to wait for the pressure drop test, but receive information about too much residual air directly after the pressure build-up
Simplification of the test
Reduction of errors through automatisatisation

The additional functions can be configured as an option package "smart MPP" in the smart memo and are billed as part of an annual fee. The following options are included:

Remote control option

The remote control option enables the automation of the testing process. The smart memo controls the MPP 70-35 and performs almost all steps of the test automatically. This simplifies the process and reduces errors. You can start the test directly at the device and the smart memo takes control of the pump as well as the right time for pressure control and maintenance.

Option air volume determination

The air volume determination is an innovative function that provides you with information about the residual air in the pipeline directly after the pressurisation phase. This saves you time as you do not have to wait for the pressure drop test to determine if there is too much residual air. This function is based on physical equations that describe the processes in the pipeline and provides reliable results that are independent of the implementation and personnel on site.

The option package includes the use of the additional functions "Option remote control" and "Option air volume determination" in the smart memo. The period of use is one year. The option package can only be used with an additional connection cable and an upgrade for the smart memo. The smart memo does not have to be sent to us for the upgrade. You simply order the smart memo as usual via the internal sales service and can easily carry out the update in the Esders Connect app. In the future, it will also be possible to book and cancel it in Esders Connect.

* These functions are available for all water pressure tests and all procedures of options DVGW W 400-2, ÖVGW W 101 and EN 805.

Do you already know our EDS2 automatic drain module?

Together with the remote control of the MPP by the smart memo, you can use it to perform fully automatic pressure tests. Avoid errors, save time and have the test performed automatically.
