Flow control solutions for cement handling

Cement is by nature extremely abrasive substance which affects all parts of the manufacturing process. Reliable flow control for cement handling is crucial. Our abrasive-resistant Flowrox™ slurry pumps, control and shut-off valves are therefore ideal for cement industry. Proven performance of Flowrox™ valves and pumps have shown in more than 5500 delivered products which boost the process performance in several hundred cement plants.

Common challenges

The performance of any reliable process depends on its components. What can first seem like an affordable flow control equipment, can quickly turn into big maintenance costs and downtime. The importance of the right selection is even more apparent when it comes to very abrasive mediums such as cement powder, slurries and grinding aid chemicals.

Cement is typically abrasive and difficult to handle even at low process pressure. Abrasive particles and high velocity causes short service intervals and operational issues, especially common for conventional flow control equipment. This inevitably leads to unwanted costs and downtime.

Reliable flow control equipment for abrasive slurry handling

In the long run, it is essential for flow control equipment to be reliable and to have a low total cost of ownership throughout lifetime. This does not only reduce spare part consumption, but also significantly reduces maintenance costs and downtime. Our Flowrox heavy duty pumps and valves are built to last in harsh process conditions found in cement processes. The robust products are designed to withstand high wear caused by abrasive mediums containing particles and powders. Wearing is effectively limited to the elastomer sleeve or hose found inside pinch valves and hose pumps.

Our heavy-duty flow control products are found in various dry and wet cement processes:

Pneumatic conveying
Silo feed/ discharge
Storage tanks
Process pipelines
Pump isolation
Bagging
Grinding aid dosing
Chemical dosing duties

Our offering for cement handling

Flowrox™ PVG and PVEG pinch valves

Flowrox PVG and PVEG pinch valves are robust and cost effective with simple, single-sided closing mechanism. PVG valve has a strong valve body and opening tags in the sleeve as a standard. PVEG valve has a corrosion resistant and light-weight plastic body. Through the reliability and structure, both kinds of valves offer substantial savings based on improved performance, long service lifetime and low total cost of ownership. Flowrox PVG and PVEG valves are ideal for low cycle applications involving abrasion, corrosion and aggressive slurries

Flowrox™ heavy duty pinch valves

Flowrox PV, PVE and PVE/S heavy duty pinch valves are designed for shut off and control applications involving abrasive or corrosive slurries, powders or granular substances. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the center line. Bubble tight shut-off is provided even if solids have built up on the sleeve wall.

Flowrox™ slurry knife gate valves

Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.

Flowrox™ LPP-T peristaltic pumps

Flowrox LPP-T transfer pumps incorporate advanced single roller design which eliminates friction and lowers energy consumption. They are ideal for pumping various slurries and dosing a wide range of abrasive, corrosive, viscous or crystallizing media.
