Overview

Welltech’s Bypass Division specialises in the successful pumping and bypassing of sewer and waste water across the nation and internationally. This division’s establishment has largely been advanced by an industry in dire need for a large scale operator with the capacity to manage flow rates in excess 10,000L/sec. 

Being able to pump high flow rates is only the beginning. We understand and embrace that to successfully carry out large scale Bypass operations, all details and possible scenarios must be identified and understood. Welltech’s Bypass Division ensures that each project component is considered, planned and executed using the most advanced equipment and practices to deliver incident free, completely controlled Bypass solutions.

Welltech’s research and development team constantly source and develop the latest equipment and technology available around the world. Once identified our Bypass division employs this most up to date technology and pumping equipment into the renowned fleet. 

Clients understand that once the Welltech team have developed, endorsed and introduced a new product into the fleet, it is guaranteed to produce reliable, quality results.

Welltech acknowledges and appreciates the complexities of delivering Bypass projects which are always of a highly sensitive nature.Welltech bring together our Management, Design and Engineering Teams to collaboratively analyse each project in detail.

With all potential projects, our in-house drafting division first prepare 3D dimensional layout images which provide ourselves and our clients a clear understanding of exact setup, footprints and layouts onsite.

On the award of a project the drafting team further produce detailed P&ID’s, material take off lists, site layout plans and fabrication drawings for any/all items. The Design Team ensure our clients understand exactly how and what the site will look like once the system has been installed.

Fleet of Equipment

Welltech’s fleet of specialised Bypass pumping equipment is predominantly Hidrostal and Flygt “N” series waste water pumps.

Hidrostal are the world leaders in waste water pump design and reliability. The Hidrostal pumps have screw impeller geometry and free passage design that can handle objects and laden liquids especially those solids that are raggy and fibrous which are prevalent in domestic and industrial waste-water.

Our fleet is constantly growing, we have pumps capable of pumping from 2L/sec through to the newest addition to our fleet – our Hidrostal “Vasto Venti’s”.

The “Vasto Venti”s” are capable of pumping individual flow rates in excess of 1,400L/sec.

Every pump in our fleet has an identical twin to act as its contingency backup.

Our fleet’s capacity has the ability to pump in excess of 10,000L/sec.

The fleet not only consists of pumps, we also have a vast range of the latest state of the art VF Drives fitted with SCADA telemetry and alarm systems. These drives can be interfaced with all Water Authorities control centers enabling complete clarity of site conditions at all times.

Some of our other equipment includes;

  • Magflo flow monitoring spools

  • Lampe pipe plugs (up to 3600mm diameter)

  • Valves and fittings through to 900mm

  • Custom, prefabricated temporary wet well pump stations
