ACP Pumps

Expertise, Reliability & Research

Jiangsu kaifeng has rich experience in providing inno-vativepumping solutions to business partners in the following industries:

Expertise
Jiangsu kaifeng'success is founded on expertise.Our know how and competitiveness is based on close cooperation with the world's leading pulp and paper producers, and engineering companies. These same principals have also led to success in the food.metals and fertilizer markets as well as other related industries. Jiangsu kaifeng is your safest choice for every pumping application in your mill or factory.


Reliabililty
The reliability of your pumping system depends on the product design,the manu-facturing and delivery process,the right hydraulic selection , aftermarket service and support. Just ringt, our success bassed on these points.


Research
Research and development have always received top prior-ity at Jiangsu kaifeng. Jiangsu kaifeng focuses on customer demand,we select the best matched with diffierent applications for Pulp &paper,Metal,Mining,Food.

Other corrosion resistant cast steels available on special request.

Other Pumps
•    The non-clogging and the wear resistant pumps from the ACP-P-plus series can be used in special applications as follows :
•    The ACP-CL series pumps with central support mount are intended for pumping liquids with high temperature.
•    The ACP-W series pumps feature specially designed wear resistant hydraulics with materials that can withstand the most abrasive and erosive pumping applications.

Standardization
All jiangsu kaifeng ACP pumps have the same basic design using common components. Only 7 bearing units forthe whole ACP series are needed to coverthe pumping applicationsin most industries.The hydraulics (casing and impeller) are tailor made according to the pumped liquid and pumping application. Casing cover , sealing parts, coupling as well as the common baseplate are highly standardized.High modular inter-changeability gives lower spare inventory costs.

Hydraulic Design

•    The jiangsu kaifeng ACP product line offers a wide range of hydraulic sizesto guarantee minimum power consumption.
•    Balance holes in the impeller are used to stabilize the pressure in the seal chamber.The balance holes in opent impeller can be plugged to optimize the shaft seal environment,reduce vibration,increase pump's life.
•    The impellers have several designs, open, closed.sem-open type, to satisfy pumping liquid with solid,pulp,sludge an so on.
•    The back vanes of the impeller keep the area between the impeller and the casing cover clean， and reduce axial loading on the bearings,and increase pump's life.

Shaft Sealing

Dynamic seal
Dynamic Seal is specially designed for fi brous liquids such as paper stock and other difficult but commonly pumped liquids. The Dynamic Seal requires no external sealing water. It is essentially maintenance free and offers outstanding reliability.

Mechanical seals
Various mechanical seal confi gurations are available. A single mechani-cal seal is used for many applications with no circulation liquid ushing with internal/external circulation liquid or with grease is available. For extremely demanding liquids and application, double mechanical seals can be selected. Sealing liquid from an external source is required.

Gland packing
Gland packing with external ushing prevents the pumped liquid frompenetrating into the seal housing.The pressurised ushing liquidcauses it to ow into the pumped liquid.Alternatively the external ushing liquid can have a seperate outlet connection.

Sealing Water Equipment
The concept for sealing water equipment meets all the requirements demanded by the pumped liquid or the shaft seal. All general pumping solutions can be covered by just four different options. Special materials to take into account corrosive environments ensure reliable, operation in extreme circumstances.
