We need snow!

The challenge.
A customer of ours had a health and safety nightmare, potentially, creating snow! The site was a film set requiring large amounts of snow. The problem was running flameproofed electrics around the site, cables, high voltage etc. In fact this was banned before it started.

However the high pressure needed for the job required industrial pumps, and in stainless steel to cope with the liquids being handled.

Cougar’s solution.
We chose vertical in-line multistage pumps with all stainless steel wetted components, and instead of using their normal electric motors used air driven motors. Non-standard couplings and motor stools were fabricated to allow the mating of the pump and drive.

The air motors run from a compressed air source and whilst not as efficient as a direct electrical source it does mean the job could be safely accomplished with only running an air hose. Also, the air drives have other advantages in that they can be regulated to run at any speed, either under or over that normally rated for the pump without inverters or any other electrical controls, merely using an air valve.

Customer benefits.
For little more than the cost of the manufacturers standard electrical drive we were able to save many thousands of pounds in electrical installation costs, and importantly meet all of the health and safety requirements on a sensitive site.

Pipe connection materials

After selling Bucks Railway Centre in Quainton a pump Back in December 2016, they recently got back in touch with us as they needed some help with some pipe connection materials.

We stepped up to the (foot)plate and sourced pipe and fittings including quick release couplings and bandseal adaptors which our engineers refer to as Elephant’s feet!! – you can see why below!

Float Switches

10m float switches in plastic casing freely suspended at the desired height from its own cable. When the liquid level reaches the regulator, the casing tilts and the mechanical switch closes or breaks the circuit.

Valves

A range of valves available including:

• Gate Valves
For on/off control, with low pressure drop

• Butterfly Valves
For flow regulation in large pipe diameters

• Non return valves
Enable medium flow in only one desired direction

Mechanical seals

There are many types of mechanical seals you might use. Just take a look below.

Don’t they all look shiny?

You should see them when we get to replace them after years of turning in the dark, hot, cold, or nasty! Shiny new ones available for all purposes.
