Stations of "PT" series - stations based on highly efficient self-priming pumps. The design of PT series pumps for needle filter dewatering allows both vertical and horizontal dewatering. These pumps can pump air, water or a mixture of water and air without an additional self-priming system. In addition, these pumps can run dry for an unlimited amount of time without damage or wear to pump parts.
Lightweight, compact and virtually silent diesel driven piston pumping units in a noise-absorbing housing are the most reliable and economical needle filter dewatering solution on the world market.
Diesel pumping units CSN comply with the technical regulations of the customs union: TR CU 010/2011 "On the safety of machinery and equipment." The climatic version of the pump unit is UHL GOST 15150-69 with an ambient temperature from -10°C to +50°C.
The warranty period is 18 months from the date of shipment or 12 months from the date of commissioning or 2000 operating hours, whichever comes first.
BBA piston pumps operate purely mechanically, on the principle of a pressure pump. Pistons with leather cuffs move inside heavy stainless steel cylinders. A convenient valve system opens and closes the pump chambers, and a gear system with an intelligent lubrication system ensures the durability of the structure. The low-speed pump (60 strokes of the piston per minute) works almost without wear.
The pump works with a conventional shaft packing. An expensive mechanical seal is not required. Thanks to this, the pump is able to run dry without restrictions and damage: this is one of the features that is most appreciated by specialists in dewatering with wellpoints.
