Back in the 1990s, SEP was founded on the basis of the efficiency of factory fabrication, as opposed to trying to build every type of assembly on site – specifically, as we now understand it, pump initiation boards (PIBs).
Although this product group has since been overtaken by strong growth in air compressors and Zone Guardian, PIBs are still an important and significant part of our business.
Not only this, but we can (and do!) argue that ours are the best in the business, for the following reasons:
- Both our double-switch sprinkler boards, and our single-switch wet riser boards are the most compact available.
- Our sprinkler boards use a unique 4-port selector valve, which means we have around 1/3rd fewer components – this is turn means around 1/3rd small and 1/3rd lighter, and of course fewer leaks.
- Our barrel nipples are made just for us, and galvanised post-production, which means no rusty threads and unsightly printing.
- The polypropylene backboard is impervious to corrosion, permanently.
What else makes us special?
One key thing is that ALL of our pump initiation boards are designed, built and tested by us – here in Stockport – which means that if you want something different then you can!
- Open CPVC or closed fully galvanised drain? It’s an everyday job!
- Different labels? We have many!
- 11 bar switches for lower pressure systems? Not only yes, but from stock!
- Pre-piped up inlets to save time? If that’s what you want!
- Full stainless & brass construction? Yes, you can see one above top-right!
- Pump-Jockey-Jockey-Pump, all on one board in that order? Yes, photo at bottom of above collage, but we can do whatever suits your design.
So, not only are we good at what we do, we can give you exactly what you want, and quickly – challenge us now by dropping us an email or using our Contact Us form to enquire about our bespoke initiation boards.
