流量控制行家Larox Flowsys的LPP-D蠕动泵现在有½,¾英寸和1英寸三种尺寸类型投放水和废水市场。1/2英寸泵的流速为2.6gpm，3/4英寸崩的流速为4.4gpm，1英寸泵的流速则是8.8gpm。
Larox称带有旋转设计的LPP和LPP-D泵和市场上任何其他的蠕动泵有着很大的不同。据悉，在所有的蠕动泵中此泵有着单位压缩周期内最高的流量，低摩擦性能的滚筒设计在每次翻转中仅会压缩一次软管，和传统的软管泵相比，这种设计可以使软管的使用寿命增长4倍。据公司介绍，在所有的蠕动泵中它还有着最低的甘油消费（96%）。和其他蠕动泵相比，它还有着极低的能量消耗，以相对小的泵身拥有相对高的流速。而且，即使它以最高的速度来工作，也不必担心软管会损坏。
此蠕动泵适合于大部分饮料业，市政和工业废除的特殊需求，这些特殊的需求主要包括，石灰泥浆、明矾、氯化铁、氨水、淤泥等等。
New sizes for Larox peristaltic pump
Flow control specialist Larox Flowsys"s LPP-D peristaltic pump is now available in ½, ¾ inch and 1 inch sizes for the water and wastewater market. The ½ inch pump has a flow rate of 2.6 gpm, while the ¾ inch has a flow rate of 4.4 gpm and the 1 inch a flow rate of 8.8gpm.
Larox says that its LPP and LPP-D pumps incorporate a rolling design is different from that of any other peristaltic pump on the market. The pump reportedly has the highest flow per compression of any peristaltic pump and the low-friction roller design compresses hose only once per revolution, which can give up to five times the hose life when compared to conventional hosepumps. It also maintains the lowest glycerin consumption of any peristaltic pump (96% less), the company says. It has ultra-low energy consumption when compared to other peristaltic pumps and maintains higher flow rates from a smaller pump size. It can also pump at the higher end of its speed range without fear of damaging the hose.
The pumps are suitable for most potable, municipal and industrial wastewater applications with applications including: lime slurry; alum; ferric chloride; sodium bisulfite; aqueous ammonia, fluoride potassium permanganate; sludge; under flow thickeners; lime slurry and sodium hypochlorite and metering.
