Van Walt Environmental Connect Issue Two

It’s back...

Turkish Delight

The Grundfos MP1 environmental sampling pump system has been around in different iterations for as long as we can remember. Some three years ago Grundfos, who have an annual production of more than 16 million pump units and is one of the world’s leading pump

manufacturers, decided to cease production of the MP1. For all those involved in environmental research this was a great disappointment. We’re delighted therefore to let you know that through an agreement with Royal Eijkelkamp whom Van Walt represent in the UK, Ireland, Spain and New Zealand, the phoenix has risen from the ashes and is being manufactured again. ... return of the MP1 Pump • High pumping capacity for purging, slow pumping for sampling • Pumps to up to 90m head of water in 50 mm (2 inch) diameter or larger wells • Easy to install • Step-less control for flow rates from 100ml to 34 litres per minute • Resistant to corrosive liquids • Pump is stainless steel and the cord is teflon coated so can be easily decontaminated • Can be used for sampling and purging deep wells • Individual elements available or as a complete set. The MP1 was generally regarded as the pinnacle of groundwater sampling pumps; powerful, efficient and capable of pumping to a theoretical 90 metres head of water and small enough to fit in a 50mm/2” well. For high flow purging and sampling in deep wells it has never been equalled. At Van Walt we are well trained in the use, maintenance and repair of the MP1 and we are delighted to be able to offer you these systems again. We have even put a new video together to help you maintain your MP1 pump in top condition. Aside from the individual components; from the pump replacements to frequency converters and cables; we will also be able to offer complete sets comprising the VFD, pump, cable and discharge tube on

Think of Turkey and you usually think of sunshine but the temperature, at -15*C hit us as soon as we exited Ankara airport and the first thoughts were whether we had packed enough warm clothes for site work and the installation of a remote telemetry system in an isolated, mountainous area in the north of Turkey. Our objective was to help with the installation of and to train local operatives in the use of a vanwalt CONNECT system. The system was fitted for a water authority who need to collect water level and turbidity data from a distribution facility in Northern Turkey. An important element of this remote monitoring system is that the company can monitor changes without having to go onsite. Every 15 minutes recordings are taken and hourly uploaded to the server where it can be accessed at any time, because any changes to the level and quality may have a direct impact on local drinking water supplies. I love Turkish coffee, hot and very sweet. It warms the soul and the sugar and caffeine mixture hits the brain in just the right way. Unfortunately, our 4-star hotel served slop which they described as “delicious continental

coffee”, so, slightly grumpy we set off on the motorway heading north. It was snowing hard and for the first time in my life I experienced the windscreen freezing over, slowly at first but progressively, until all but a tiny roundel became opaque. Luckily we had an excellent driver in our colleague and host Kadir. Some 4 hours later we arrived at our destination and coffee! Adnan and Caner had prepared well for us with the system, boxes and components being sent ahead of us. When we arrived on site the vanwalt CONNECT box was on a post, solar panel in place and the couple of 100 odd metres of cables neatly within a buried conduit. In fact, all we had to do was connect the battery, reset the time and wait for the meat to be fully cooked on the barbecue. In the meantime data was streaming in and continues to do so. This was one of the most straightforward installations we’ve had this year. After a night in a delightful period guest house we were given the opportunity of visiting Safranbolu, a world heritage site. The Old Town preserves many old buildings containing registered historical artefacts. There is plenty to see including museums, 25 mosques,

five tombs, eight historical fountains, five Turkish baths, three caravanserais (a roadside inn where travellers (Caravaners) could rest and recover from the day’s journey), one historical clock tower, one sundial and hundreds of houses and mansions as well as mounds of ancient settlements, rock tombs and historical bridges - plenty of opportunities for an enthusiastic photographer! The name of the town Safranbolu derives from ‘saffron’ and the Greek word ‘polis’ (city), a trading place and centre for growing saffron. Today saffron is still grown and the village of Davutobası which is 22 km east of Safranbolu claims to have some of the best quality saffron in the world. Time to see some of the country and its amazing history was the icing on the cake and our thanks go to Kadir, Adnan and Caner for having made our visit so successful and interesting.

a reel with either Teflon or PE tube in standard set lengths of 30, 60 and 90 metres. A suitable generator is an important component of the system and we will continue to offer the appropriate Honda “suitcase” type genny.
