The fact:

A lot of end users feel “locked in” to a specific pump manufacturer because their pump installation has already been fitted with a specific base/elbow and guide rails that can accommodate only one type of waste water pump. Many of these pumps are outdated and have low efficiency standards and high maintenance costs.

PXFLOW service advantages:

The PXFLOW pump discharge flange connection and adapter have been designed for a quick and easy replacement of various different pump brands. Depending on the pump brand that needs to be replaced there is an equivalent PXFLOW pump that can either use a PXFLOW adapter, (ideal for Flygt & Pumpex discharge elbow base with 2” or 3” guide rails), or can be installed using the existing flange adapter and base discharge elbow.

Modifications according customer needs:

Sometimes the flange bolt hole pattern can be different from pump to pump.

In order to overcome this issue PXFLOW pumps can be ordered with a solid discharge flange so the customer can specify the appropriate bolt hole pattern that is needed for their installation to match their corresponding discharge base elbow. We can also manufacture custom size flanges, upon request, to match specific customer needs. A major advantage that we have at PXFLOW pumps is that we can manufacture larger than the standard flange sizes in our foundry.

 Long experience in pump business:

Carlo Wong is our distributor in Hong Kong and has more than 15 years of experience with Pumpex pumps. He has successfully replaced a large number of existing pumps like Pumpex, Flygt, ABS, Grundfos, EMU, Yeoman, Homa with PXFLOW waste water pumps.

Examples:

Chung Hom Kok Sewage Pumping Station in Hong Kong

Pump type:PX4-150.0+75kW Vortex impeller in SS316

 Special discharge flange DN200

 Duty point :93m3/h at 61m

 Replaced brand: PUMPEX K204

EMSD – Butterfly Beach Laundry –Hong Kong Pump type:PX2-100.0+7,5kW

Single channel impeller

 Drilled flange and modification acc. existed adapter

 Duty point :120m3/h at 13m

 Replaced brand: YEOMAN 4153

The problem:

The vast majority of the pump stations in Greece are located at sea level but are inefficient due to long discharge pipes or because the discharge end of the pipe is located at a high elevation. Most of them are located in tourist areas with generally low flow needs.

This combination, of low flow and high head, is posing a particular problem to most pump manufactures. Until now there was no ideal pump type for this kind of demanding pumping situation. Some manufactures are offering high speed pumps (2 pole) equipped with channel impellers but with small ball passage (30-40mm) and a duty point that is located left of the curve. The channel impeller is fitted with wear rings or wear plates, (open channel impeller), so they can reduce the gap between the impeller and the volute. Eventually when the gap widens significantly the pump performance drops dramatically and the duty point is starting to move to the left of the curve.

The solution:

The PXFLOW pump series is fitted with a high head Vortex impeller.

The advantage of Vortex impellers vs. channel impellers are

• The vortex impeller pump does not have any wear ring to wear down, and therefore maintain the efficiency much longer with power savings and maintenance savings as a result.
• The vortex impeller runs very smooth
• Larger ball passage

In one of the most beautiful areas in Greece at Elounda
bay area (Ag. Nikolaos) in the island of Crete we have installed and have been operating a high head pump(PX3-80 vortex 2 +32kw type) with an operation point of

30m3/h at 81 m.Recently a second pump was installed in the pumping station, were retrofitted with our

original discharge connection brackets (DCB).

Γιορτάζουμε την επέτειο των 50 χρόνων!

Φέτος ο ΠΑΠΑΝΤΩΝΑΤΟΣ, κατασκευαστής της σειράς υποβρυχίων αντλιών λυμάτων PXFLOW και γεωτρήσεων FLOWPAP γιορτάζει την επέτειο των 50 χρόνων. Το ξεκίνημα άρχισε το 1963 στην Ελλάδα από τον Η.Ν.Παπαντωνατο, ο οποίος αφού εργάστηκε από το 1950 έως το 1962 στην KSB στην Ελλάδα, συνέχισε με τις υποβρύχιες αντλίες και κινητήρες Pleuger.

Αισθανόμαστε υπερήφανοι διότι είμαστε από τους παλαιότερους αντιπροσώπους των προϊόντων Pleuger παγκοσμίως. Λόγω των υψηλών δασμών και της υποτίμησης του εθνικού νομίσματος άρχισε την  κατασκευή φυγοκεντρικών αντλιών μονοβαθμίων, πολυβαθμίων καθώς  και στροβίλων γεωτρήσεων.

Αρχές του 70   επικεντρώθηκε αποκλειστικά στην κατασκευή υποβρυχίων αντλιών γεωτρήσεων με την πλήρη υποστήριξη της Pleuger.

Το 2004 οι δύο υιοί του Η.Ν.Παπαντωνατου ξεκίνησαν την κατασκευή των υποβρυχίων αντλιών λυμάτων PXFLOW.

 Με εμπειρία μισού αιώνα στον τομέα των υποβρυχίων αντλιών συνεχίζουμε να βελτιώνουμε και να αναπτύσσουμε την υπάρχουσα σειρά χρησιμοποιώντας κινητήρες υψηλής απόδοσης και στοχεύοντας στην κατασκευή μεγαλύτερων σε απόδοση και ισχύ αντλιών και κινητήρων.
