Installation Plan and Engineering Know-How – KWP Series
As part of the complete technology transfer package, Pumpnix provides a detailed Installation Plan for each KWP pump type. These engineering documents go far beyond drawings—they serve as a core reference for the factory engineering team, covering:
Precise nozzle dimensions (suction and discharge) with ASME/Class 150 standards
Baseplate layout with foundation bolt positioning and anchoring details
Alignment and clearance tolerances for coupling, motor, and pump shaft
Maximum allowable nozzle loads (forces and moments) defined according to ISO 5199 / ISO 9905
Overall dimensions and weights, supporting proper lifting, handling, and installation procedures
These installation documents guarantee accurate pump mounting, mechanical integrity, and long-term operational reliability in demanding industrial applications such as process water, wastewater, and slurry handling.
With its proven expertise in engineering and pump manufacturing, Pumpnix not only provides these plans but also transfers the full know-how behind them. Your technical team will be trained to interpret, apply, and maintain these standards, while a structured technical archive is established for every pump type within your production line.

Hydraulic Performance & Coverage Charts
Hydraulic Performance Charts and Technical Documentation – KWP Series
As part of the complete technology transfer package, Pumpnix provides accurate hydraulic performance coverage charts for every KWP pump type. These charts clearly illustrate the operating envelope of the pumps across three standard rotational speeds (2900 / 1450 / 960 RPM) and are also defined according to impeller trim diameters, ensuring optimal adaptation to project-specific duty points.
The diagrams and charts contain all key hydraulic parameters, including:
Head vs. flow rate (Q) characteristics
Pump shaft power and motor sizing requirements
NPSH curves for reliable cavitation-free operation
Hydraulic efficiency ranges at different operating conditions
In addition, detailed datasheets are prepared for each KWP model, covering:
Operating data (flow, head, NPSH, efficiency)
Mechanical design parameters (impeller size, vane count, nozzle positions)
Motor, coupling, and baseplate specifications
Complete parts list for production and after-sales support
These documents are indispensable during the pump factory setup phase, providing a solid basis for accurate pump selection, efficient production planning, and effective sales engineering.
At Pumpnix, we don’t just hand over these charts and datasheets — we integrate them into your engineering department, train your technical and sales staff, and help establish a structured engineering archive for every pump family in your product portfolio.
The sample datasheets and performance charts shown above are taken from the KWP series, representing actual technical documentation that supports both learning and practical implementation.

Sectional Drawings and Design Features – KWP Series
As part of the knowledge transfer package, Pumpnix provides detailed sectional drawings for the KWP series. These technical illustrations go beyond visualizing the pump’s internal construction — they highlight the key design features that ensure reliability, efficiency, and maintainability in industrial operation.
The sectional diagrams showcase:
Back-pull-out design, allowing the pump to be dismantled without removing the casing from the pipeline.
Channel-type impeller with front vanes, ensuring high hydraulic efficiency and reduced wear.
Inspection holes and wear-resistant plates, enabling easier maintenance and longer service life.
Integrated mechanical seal chambers (A-type cover) for improved sealing, automatic venting, and reliable operation under demanding conditions.
Heavy-duty bearing assembly, dimensioned for extended lifetime (over 17,500 hours).
Constant-level oil lubrication system for bearings, ensuring stable performance.
Reinforced modular construction, reducing spare part variety and enabling faster service.
These drawings and notes serve as training tools for your engineering team, giving them a deep understanding of the KWP pump design. By mastering these sectional views, your staff will not only learn how to assemble and maintain the pumps but also gain valuable insights into design philosophy and long-term durability.
At Pumpnix, we make sure your engineers don’t just see the drawings — they fully understand the engineering logic behind every feature
Exploded View & Component Identification – KWP Series
As part of the complete technology transfer package, Pumpnix provides detailed exploded view diagrams and comprehensive Bills of Materials (BOM) for the KWP pump series.
The exploded view shown here highlights every component of the pump — from the volute casing, impeller, and shaft assembly to the bearing bracket, seals, gaskets, and fastening hardware. Each item is precisely numbered and listed with a standardized part code, ensuring full traceability and consistency in manufacturing.
These diagrams and part lists serve as critical resources for:
Accurate assembly and reassembly during manufacturing or maintenance
Identification of service parts and spare part management
In-house component production or reverse engineering
Technical training for engineering, assembly, and service teams
By combining these exploded views with 3D CAD models and workshop documentation, Pumpnix ensures that your factory gains the complete capability to independently produce, assemble, and maintain the KWP series.
Dimensional Drawings – KWP Series
As part of the complete technology transfer package, Pumpnix delivers precise dimensional drawings for the KWP non-clogging pump series. These technical drawings include all critical installation parameters, such as:
Baseplate and foundation bolt layouts
Suction and discharge nozzle positions and flange dimensions
Shaft end geometry and keyway sizes (DIN 6885 compliance)
Back pull-out clearances for maintenance without removing the motor
Each pump size within the KWP range (from DN 40 up to DN 923) is documented with detailed dimensional data and categorized by bearing bracket type. These drawings ensure that your engineering team can accurately design foundations, align couplings, and plan piping systems with full confidence.
At Pumpnix, we don’t just provide the dimensional data — we transfer the know-how required to interpret and apply it effectively. This enables your production team to independently install, align, and maintain every KWP pump model with long-term reliability.
