Kaifeng Pump Valve
Medium - Consistency Pump - KMC
Series
No External
Vacuum Pump Required for Maximum
Efficiency
For decades, Kaifeng Pump and Valve
has enjoyed a well - deserved
reputation for its excellence in the
design and innovation of centrifugal
pumps.
As a supplier that provides a
comprehensive product portfolio for
the pulp and paper industry, we
possess experts who are highly
proficient in the relevant process
technologies. This expertise serves
to establish a robust and enduring
foundation for our successful
advancement within the pulp and
paper industry.
The newly - developed KMC series
medium - consistency pumps by
Kaifeng Pump and Valve have set a
new benchmark in transporting medium
- consistency pulp suspensions.
It fully meets the high-end
customers' requirements in multiple
aspects such as efficiency, service
life, ease of maintenance, economic
benefits, and reliability.
Numerous practical applications
demonstrate that the KMC series
medium-consistency pumps of Kaifeng
Pump and Valve deliver outstanding
economic benefits, achieving
one-third energy consumption savings
compared to pumps from other brands.

Kaifeng Pump Valve's New
Medium-Consistency Technology
Pumping medium-consistency slurries
in the pulp and paper industry is a
complex task, and Kaifeng Pump Valve
provides a complete system designed
according to customer requirements.
Revolutionary Design Achieves
Ultra-High Reliability
Medium-consistency pumps are
critical components in bleaching
lines, pulp lines, and fiber
recovery lines, directly impacting
overall plant production capacity.
The KMC series pumps from Kaifeng
Pump Valve feature a single-shaft
design that eliminates the need for
external vacuum pumps (in most
cases), delivering not only
exceptional reliability and
robustness but also unparalleled
operational simplicity (the
degassing valve requires only basic
on/off logic).
SMARTSEP - A New Degassing System
Kaifeng Pump Valve was the first to
propose and practically validate a
solution for pumping
medium-consistency pulp using
single-shaft pumps. With the new
degassing system, no pressure
differential control is required to
adjust the degassing valve opening
under any operating conditions, and
there is no fiber loss (even during
low-concentration startup). The
control of the degassing valve is
extremely simple: open the valve
when the pump is running, and close
it when the pump stops. Pressure
differential control for the
degassing valve opening is only
required in extremely rare cases
(e.g., booster pump applications).
The main advantages are as follows:
• High Efficiency (>70%):
Significantly exceeding the industry
average, thereby reducing energy
consumption.
• Extremely Easy to Operate:
Virtually no fiber loss during the
degassing process (at any
concentration).
• Good Slurry Fluidization:
Effectively maintains fluidized
state of the slurry.
• No External Vacuum Pump
Required in Most Cases:
Simplifies the system, reduces
investment costs.
Exceptional R&D Capability
Extensive testing conducted on
in-house test platforms has
optimized the degassing process and
enhanced efficiency.
With an efficiency exceeding 70% and
minimal components, the
effectiveness of our pump technology
is significantly elevated.
The modular assembly of Kaifeng Pump
Valve’s KMC series pumps further
highlights the advantages of high
energy efficiency and simple
maintenance.
