Pump manufacturers

KRIWAN listens and understands the demands of the market

Manufacturers build their pumps in a range of different versions according to the demands of the market. There are an enormous number of different designs, applications, conveyed fluids, supply voltages, and so on. 

 

The benefits of KRIWAN’s integrated pump protection systems:

  • High-quality, compact, extremely long-lasting, precise temperature and fluid sensors as well as sensors for electrical voltage and current 
  • A wide range of electronic protection relays with different functional scopes 
  • USB, ModBus, and Internet communication interfaces on protective relays
  • More safety on site  
  • Reduces claims and makes testing easier 
  • Products with a reputation for strength and durability 
  • Added value for system engineers because of significantly reduced commissioning time and diagnostics for service technicians 
  • More turnover with attractive bundles and up-selling (pump + sensors + protection device)
  • Modern guarantee, maintenance, and service models based on operating data 
  • Preset and parameterizable properties 
  • Approvals such as UL, ATEX, SIL, and CE

 

 

With its new generation of INT69 Diagnosis, Kriwan has made its flagship protection module even more powerful.

Plant engineering

Planning companies and plant engineers utilize their considerable engineering expertise to set up processing plants on behalf of their operators. Pumps are used in an enormous range of different plants: the chemical industry, food and beverages, water supply and disposal – these are just a few examples of the areas in which they are used. That is why Kriwan components convince in terms of cost, durability, functional scope, and the time it takes to commission them. 

Benefits in process engineering:

  • Compact, durable, precise sensors for the monitoring of temperatures and fluids, for integration into PLCs and protective relays, and for stand-alone use 
  • Wide range of high-end standard protective devices 
  • Customized, parameterizable solutions available if at least 100 protective relays are needed for pumps each year 
  • A focus in the PLC on the relevant operating parameters and processes while securely protecting pumps 
  • Simple, integrated diagnostics 
  • Quick to commission 
  • Simplified approval testing since the pump / protection device combination possesses the necessary approvals (such as functional safety compliant with VDE and UL), and these do not need to be covered by the PLC 
  • Protective relays cannot be tampered with on site (no potentiometers or switches that can be adjusted) 
  • Competitive advantage on account of quicker execution in projects and reduced workload

Operators

  • An easy way of establishing a uniform, secure protection concept throughout for pumps as an investment asset and process-critical component for many applications
  • More process and production security since many pumps do not need a redundant back-up
  • Validated maintenance, service, and spare parts planning based on operating periods, fault statistics, and trends in temperature and current consumption
  • Wide range of solutions involving original and retrofitted equipment
  • Quick to install; plant only needs to shut down briefly, no intervention in automation, an ideal scenario during commissioning and scheduled maintenance
