Long-Coupled Pumps
The BakerFlow series is a range of general-purpose centrifugal pumps designed and built for long service and low maintenance in a wide range of 'clear liquid' applications.
The BakerFlow (aka SW) series of pumps are commonly coupled to electric motors and diesel engines via a spacer coupling. This is part of the back-pull-out (BPO) design, which allows the pump rotating unit to be removed without disturbing the pipe connections.
Using a spacer-type coupling, the primer mover (the motor/engine) is also undisturbed. This reduces service time and production losses.
Features
BakerFlow pumps are designed and manufactured to one of the world’s most widely accepted pump standards, DIN 24255/EN733, as well as ISO 2858.
We manufacture with a stainless steel impeller.
Options:
- Bareshaft pump only
- Complete pumpset
- Size range between DN32 to DN300
- Flow rates between 5-300 litres per second
- 16bar, 25bar, or 30bar ratings
- Higher grade material options available depending on the pressure
Frequently asked Questions
- How are long-coupled pumps easier to service?
Long-coupled pumps are easier to service due to the provision of the spacer coupling, allowing work to be performed on the pump and/or motor without disrupting the motor and the pipework.
- What are 2 simple tests I can do onsite to determine if my pump is cavitating?
If the needle on the pressure gauges on the suction and discharge pipework are unstable, this generally indicates the presence of air being present in the pipework. It is important not to leave the pump operating against a closed head for more than 5-10 seconds, and this should be done by a cmpetent and trained engineer or pump technician. This advice is general only, and we recommend consulting with a Masterflow engineer for further guidance.
- Is a packed gland or mechanical seal better?
While both have their pros and cons, mechanical seals are more commonly used in modern day pumps, as they are much more durable and are designed to have multiple sealing points to eliminate any leaking issues, making them a better choice for the long-term operation of your pump.
- How do I repair a mechanical seal in a pump?
Repairing or replacing a mechanical seal should only be done by experienced pump technicians. Care must be taken when fitting a mechanical seal and reassembling the pump to ensure correct fitment within the manufacture’s tolerances, and that the seal faces are in the right order.
