Scirocco Posted October 3, 2006 Report Share Posted October 3, 2006 Hi, Does anyone have a suggestion where to purchase the Rolachem squizze hose at a reasonable price? I can't belive they want more than AU$20.00 for a 15cm rubber hose. The meter probably costs a quarter of that. Cheers PS: I have a chlorine and an acid feeder and I'm going through 4 of these hose pieces each year. Quote Link to comment Share on other sites More sharing options...
dynamictiger Posted December 1, 2006 Report Share Posted December 1, 2006 The rolachem squeeze hose is a proprietary product. Whilst I can think of a dozen companies whose tubes may fit the tubes are more expensive. The rolachem tubes are actually very cheap for a chemical dosing pump part. By the way rolachem have now been bought by Hurlcon, depending on when you last purchased the product the pricing may have changed.

Tree Fern Posted December 13, 2006 Report Share Posted December 13, 2006 Hi, there are alternatives to the genuine Rolachem peristaltic pump squeeze tubes. Rolachem use a clear Tygon tube for the the chlorine and a black Butyl tube for the acid side. You can use the Butyl for the chlorine side as well - it lasts longer, but you can not use the Tygon tube on the acid side. The dimensions for the tubes are: Length = 250mm Bore = 6.4mm Wall = 3.2mm A superior and much longer lasting product is Marprene. It is made by Watson Marlow, a global pump and tubing manufacturer. Marprene is a thermoplastic elastomer and is completely compatible with hydrochloric acid and sodium hypochlorite. The Australian agent is in Wetherill Park in NSW [they also have a branch in Brisbane]. Phone - 02 9725 2733. They do mail order. Their web site: www.stauffpumps.com and www.watson-marlow.com and www.bredel.com The tubing is only available by the metre and then only in a minimum if 3 metres. It costs $57 a metre + GST. The part number for Marprene tubing as per the above dimensions is: 902.0064.032 So you can work it. Yes you have to pay more up front, but I was also finding I was having to replace the "genuine" tubes at least twice a year, and I regularly lubricate the tubes! I have found the marprene to outlast the tygon and butly by at least double if not more. Another of their web sites is: www.pumpsil.com. That lists all their tubings, applications, chemical compatabiliity. There are in fact more expensive tubing available from them - silicone, which sells for $64.70 + GST a metre. And then they sell Tygon if you wish at $31 + GST a metre. Any way, I found there service to be very good and their product to be superior - by far Now if someone could tell me where to get cheap ORP and PH probes to suit the Rolachems..........
