Hydra Cell pumps are recognised as compliant with the requirements of various national and international certification organisations, including those listed below.




“ATEX” is an abbreviation for the ATEX Directive and is short for “Atmospheres Explosibles”. It is a set of European Union regulations that are designed to ensure the safety of products being used in explosive environments.

There are two ATEX Directives (one for the manufacturer and one for the user of the equipment):

  • The ATEX 214 "equipment" Directive 2014/34/EU - Equipment and protective systems intended for use in potentially explosive atmospheres
  • The ATEX 137 "workplace" Directive 1999/92/EC - Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres

Wanner International is fully compliant with all necessary legislation, and offers a wide range of pumps to ATEX Group II, Category 2 (Zone 1) and Category 3 (Zone 2) certification.

Contact Wanner International +44 (0) 1252 816847 for further details about ATEX and the UK equivalent regulation No. 1107 compliant pumps.



The CE mark identifies compliance of Hydra-Cell pumps with the European Union's health, safety and environmental legislation, including the Safety of Machinery Directive 2006/42/EC, one of a series of mandatory standards being adopted by EU member countries.

Having demonstrated compliance with the 'Essential Health and Safety Requirements' (EHSR) Wanner is allowed to self certificate and place the CE marking on Hydra-Cell pumps.
The UKCA (UK Conformity Assessed) marking is a new UK product marking that is used for goods being placed on the market in Great Britain (England, Wales and Scotland).

Wanner International supplies marine pumps that are individually tested & certified by Det Norske Veritas (DNV), an independent maritime Classification Society. The Product Certificates outlines intended service; pump rating (in terms of flow and pressure) and service restrictions while specifying the intended destination vessel.

DNV certificated pumps from Wanner are used for a variety of marine applications including pumping and metering light, low sulphur fuels, RFOs (residual fuel oils) seawater, ballast treatments and FGD treatment chemicals. 

DNV certificated Hydra-Cell diaphragm pumps overcome the problems associated with pumping the light viscosity, low sulphur fuels (as dictated for use in Sulphur Emission Control Areas [SECAs]). Gear pumps and screw pumps lose efficiency when pumping light viscosity liquids and all pumps with dynamic seals have the potential to permit vapour escape or fuel leaks.

Like the CE logo, the Declaration of Conformity is one of the common threads throughout all the CE marking directives.

It is a confirmation by the manufacturer that the product meets the requirements of the CE Marking Directive and really is compliant. It also allows an enforcement authority to identify who is responsible for a product and what that person claims to have done to CE mark it.

A properly issued Declaration of Conformity is always issued by the product's manufacturer (or by the person responsible for selling the product in Europe) and never by a test house or Notified Body.

The effect of the Declaration is to identify an individual in the company who can be held responsible if the CE marking on a product turns out to be invalid.

Each directive has slightly different requirements for the content of its Declaration. That of Wanner International is in accordance with the Machinery Directive.




Wanner International is able to supply Hydra-Cell pumps for marine duties in compliance with the requirements of Lloyd’s Register. Certificates for these pumps, backed by independent Witness Tests, have been issued by LR for duties that include transfer of low-sulphur fuels.

LR certificated Hydra-Cell diaphragm pumps overcome difficulties associated with pumping light viscosity oils and other poor lubricants.





Supervised by Rosstandart (Federal Agency for Technical Regulation & Metrology), the new TR CU certificate now replaces GOST-R.

Covering the three states of the Customs Union - Russia, Belarus & Kazakhstan, the main objectives of the certificate is to:

  • To protect safety, health and environment of consumers & users of goods
  • To prove compliance of products to Russian and Customs Union safety requirements
  • Required for Customs clearance procedures at the Russian & CU border
  • Required for the sale and use of products in the local market

The new TR CU certificate allows for the safe use of equipment in explosive atmospheres and is mandatory for any electrical equipment that is installed or operated in hazardous or potentially explosive atmospheres in the countries.
