The robust way to pump

Finsterwalder hydraulically operated KV20 ball valve pumps, suitable for all types of free-flowing and largely homogeneous slurries, are extremely low-wear and insensitive to abrasion. Various drive modules are available, which are selected according to customer specifications.

The low-wear alternative

Ball valve pumps are characterized by a very simple design and are therefore less susceptible to faults. This applies in particular to media containing sand, as ball valve pumps do not contain any rotating parts. The KV20 is hydraulically driven and available with one or two ball valves, depending on the required flow rate.

Main features of the KV20 ball valve pump

• No rotating parts, i.e. an extremely robust and low-wear pump that is resistant to hard particles such as metal, bone and glass
• Max. Particle size up to 20 mm
• Delivery rate up to 35 m3/h
• Pressures up to 40 bar

Options

Single ball valve – High pressure option
Slower, even pumping processes, e.g. for feeding the FINSTERWALDER double-tube heat exchanger Double ball valve – High flow rate
at medium pressure Fast, large-volume pumping for applications such as feeding fermenters or loading pre-treated food waste sludge into trucks.

Web visualization

Like every other machine from Finsterwalder Umwelttechnik, the KV20 ball valve pump has a touch panel on the control cabinet and a web visualization. The machine can be easily controlled and settings can be made via the web HMI using any internet-enabled device. The process can also be monitored via this interface, which ensures process reliability.
