PUMPS
SEEPEX Big Pumps with Maintain-in-Place Technology : Smart Maintenance . Fast and Simple .
SEEPEX , global leader in design , manufacture and applications of progressive cavity ( PC ) pumps , macerators and
digital technology , continues to extend its world class portfolio of maintain-in-place pump technologies .
The new patented
BNM range of pumps with capacities up to 300 m3 / hr and discharge pressures up to 48 bar can handle flowable to highly viscous products with a high dry solids content . The design features a suction casing that enables quick and easy access for rotor and stator removal without having to dismantle the rotor side joint . As a result , maintenance time can be reduced by up to 80 % with a significant reduction in maintenance costs .
The suction casing and pressure branch remain in place , eliminating the need for pipework dismantling . The pump drive can then be quickly removed complete with mechanical seal , drive side universal joint and coupling rod .
UNIQUE PATENTED SOLUTION

Wanner announces new Hydra-Cell heavy duty , high pressure , multidiaphragm seal-less pump
Wanner has launched the Hydra- Cell ® T200 Series Medium Pressure , multi-diaphragm pump range , which in terms of flow rate and pressure are the highest performing pumps in the Hydra-Cell range and the biggest pumps ever produced by the Company . They feature a seal-less design that eliminates leaks , hazards and the expense associated with seals and packing ; lowering the cost of ownership and giving a longer service life than competitive pumping technologies . There are two models , currently , in the T200 Series , rated at 207 bar ( 3000 psi ) and 241 bar ( 3500 psi ) with maximum flows of 387 l / min ( 102.2 US gpm ) and 349 l / min ( 92.4 US gpm ) respectively . The new pumps are ideal for oil and gas production , mining operations , boiler feed and high-pressure cleaning , along with chemical and petrochemical process and transfer applications .
Hydra-Cell pumps have no dynamic seals , cups or packing to leak , wear or replace , eliminating seal maintenance costs while hazardous materials and VOCs ( volatile organic compounds ) are fully contained . The seal-less design , combined with robust check valves , also enable the pump to handle abrasive particles up to 800 microns in size and with less wear than gear , screw or plunger pumps . The Hydra-Cell T200 can operate with a closed or blocked suction line and can run dry indefinitely without damage , eliminating downtime and repair costs .

No Problem Metering Non-lubricating Liquids with Hydra-Cell
Hydra-Cell API 675 Metering Pumps have solved a problem for one of the world ’ s largest suppliers of polyurethane automotive foams
The external gear pump used to pump nonlubricating , water-based catalyst were prone to wear , exhibited low efficiency and caused unacceptable high shear within the product . Hydra-Cell API 675 diaphragm Metering Pumps , with their inherently low shear pumping action , provided the ideal solution to the problems . Since the application could not risk contamination by the hydraulic fluid , extensive testing with Mesamoll ® oil , was conducted before a Hydra-Cell Metering Solutions model P200 was installed for evaluation . This first P200 pump performed exceptionally well , eliminating the low-efficiency , high-shear , and nonlubricating pumping problems . Hydra-Cell P200 pumps are steadily replacing the gear pumps on the customer ’ s systems installed in automotive plants around the world .
