In the BBA Pumps Oil Change Overview, you will find a complete overview of the recommended oil types, fill quantities and oil change intervals for the most common BBA pumps.
Although BBA Pumps works with different brands of diesel engines, the error codes are largely universal.

The Support Document Engine Related Errors provides a clear overview of SPN (Suspect Parameter Numbers) codes. In such cases you should contact a certified person trained to work safely on high-pressure common rail diesel engines.

This depends on a number of factors, such as the contents of the suction hose (length & diameter) and also the capacity of the vacuum system. If there are no leaks in the non-return valve or suction hose, the pump will quickly draw in liquid. See this short video priming with MP50 vacuum pump.



BBA Pumps uses three different composite doors for its sound attenuated canopies. In the Door dimensions overview you will find all sizes for applying your company logo.  

Yes, all standard models of the mobile BBA pumps are ready to be mounted on a trailer.
In the overview Connect Your Pump to a Trailer, you will find all the sizes you need for a traffic-safe pump–trailer combination.

In the BBA Pumps Tightening Torques Overview, you will find the tightening torques of the most common bolted connections of BA centrifugal pumps and of the vacuum system.
The main answer to this is that a PT piston pump has been specially developed for wellpointing, making it much cheaper to achieve a dry construction pit.

We have listed all the advantages for you in the document PT piston pump versus BA dry self-priming centrifugal pump.

WARNING
In the event of a malfunction or abnormal operation, shut off the pump immediately to prevent a dangerous situation and/or damage to the unit. Below a list of “possible causes” with suggestions how you can easily solve the issue

ProblemPossible causeSolution
No flow while the pump and drive are runningThere is a leak in the suction pipeEliminate the leak
The suction pipe or strainer is cloggedClean the suction line
Inlet of the suction pipe is insufficiently submergedSubmerge the suction line more deeply
Air pockets form in the suction lineEliminate air entrapment to the extent possible
Vacuum pump does not drawInspect the condition of the vacuum pump
Non-return valve is not closing sufficientlyInspect the non-return valve most likely it is clogged
Coupling between motor and pump is defectiveReplace the coupling
ProblemPossible causeSolution
Insufficient flow while the pump and drive are runningThere is a leak in the suction pipeEliminate the leak
The suction pipe or strainer is cloggedClean the suction line
A vortex appears in the water close to the inlet of the suction pipeSubmerge the suction line more deeply or use the space hopper (skippy ball) method
The wear plate/ring is worn outAdjust or replace the wear parts
Foreign object in the impellerClean the impeller
The impeller is damagedReplace the impeller
Gas or air is released from the liquidEnsure that the liquid flows more slowly/smoothly
Pump speed is too lowIncrease diesel engine RPM or motor speed (VFD)
Incorrect direction of rotation
(only electric drive pumps)
Reverse direction of rotation
(only electric drive pumps)
ProblemPossible causeSolution
Cavitation noise in the pumpSuction height is exceeding the NPSHr of the pumpContact us to discuss the options
Poor suction pipe installationCheck the BBA Pumps Installation Tips on the website or in the manual
Velocity in the suction line is too highRecommendation maximum 4 m/s
Gas or air is released from the liquidEnsure that the liquid flows more slowly/smoothly into the pump
Pump is running too far from BEP in the performance curveCheck the specification sheet or performance curves of the pump unit
ProblemPossible causeSolution
Pump is demanding abnormal amount of power (drive is overloaded)Pump speed is too highDecrease diesel engine RPM or motor speed (VFD)
Incorrect direction of rotation
(only electric drive pumps)
Reverse direction of rotation
(only electric drive pumps)
The shafts are not in alignment with one anotherAlign the unit
Rotating parts are rubbing against stationary partsAdjust everything and align if necessary
Inadequate lubrication or insufficient lubricant in the bearing housing, possibly as a result of a leak; can be identified by higher than normal temperatureFollow good service plan
In this application the pump is not functioning in the intended rangeMake changes to the piping system, if possible Otherwise: use a different type of pump
The liquid has a higher s.g. or viscosity than that for which the pump is intendedChange temperature of liquid, if possible.
Otherwise: use a different type of pump
