2.2. General description of the machine
The Quattroflow 150 SU pump is a 4-piston diaphragm pump. The four segments of the pump
diaphragm oscillate back and forth. This alternate movement is created by a connector plate that is
arranged on a ball bearing. The ball bearing sits on an eccentric shaft. The connector plate does not
turn!
The stroke of the pistons is determined by the angle of the eccenter. There are eccentric shafts with 5°
available.
Range of flow rate: 5° eccentric shaft: appr. 1 - 180 L/hr
The product wetted pump chamber is provided for single use applications and can easily be replaced
after usage. Due to the dispose of the pump chamber after use, efforts for cleaning, validation and
risks for cross contaminations are eliminated.
Please note:
The direction of flow can be adjusted by turning the pump chamber in 90° steps.
The Quattroflow 150 SU is self-priming and can run dry. Inside the pump chamber there are no
rotating parts that might cause heating up of the product or shed particles.
The pump-motor unit is mounted on a stainless steel base plate. In case that the pump will not be
mounted on the base plate but in a frame or any other base measures have to be taken that there will
be a proper alignment of the motor and the pump.
2.3. Start-up
A Quattroflow single-use pump is delivered pre-assembled. Three plastic pump chambers are
attached to each new pump unit. One of them has to be installed according to the instructions in
Section 4.1. (replacement of the pump chamber), while the other two are for a further replacement.
Before start-up of the pump anyone should acquaint oneself with the explanations of the chapter
troubleshooting (see page 16). Only by this the defect quickly can be realized and eliminated in case
of trouble. Problems which cannot be solved or with an unknown reason should be passed on to the
manufacturer.
Prior to each use we recommend to flush the pump with a proper fluid (e.g. water or buffer).
Prior to the very first use it might make sense to clean and sanitize the pump chamber. A commercial
caustic cleaner and/or 0.1N to 0.5N NaOH can be applied. The chosen cleaning agent can be
recirculated and also stored inside the pump chamber. For flushing out of any cleaning agent do not
recirculate! Check with appropriate analytical methods the success of the flushing procedure..
Recommendation: Test run prior first use!
Before using your pump in your process perform a test run to get used to the specific
properties of the pump.
Please note: ALMATEC Maschinenbau GmbH is also building custom-made pumps and set-ups.
These modified pumps can be different from this one that is described in here. However the basic
information is applicable to all of the Quattroflow 150 SU Series pumps. Please do not hesitate to
contact us for further information.
Pay attention to a sufficiently dimensioned piping. A too small piping of the
suction line can cause cavitation as well as a loss of performance.
