The story behind Sigma Pumps
Sigma hand pumps were first produced in 1868 by Ludvík Sigmund
Production began in the small village of Lutin near the historic town of Olomouc in Czechoslovakia
Factory production included the wooden and iron stand pumps for sunken wells, pumps for town and village inhabitants, rotary, plunger and the famous K series hand pumps
The factory was then known as the Sigma Olomouc Concern Corporation
In 1894 sons Jan and František took over the firm from its founder
During World War 2 in 1942 Jan Sigmund was murdered by the Gestapo, and the company in Lutín was confiscated by the German Reich and extensively rebuilt to produce armament parts for tanks, submarines, aircraft and cars
After the war Sigma engineers and factory workers kept pace with rapid development in every branch of the pumping industry and became highly acclaimed for their design of progressive equipment
The Sigma production range soon included centrifugal and diaphragm pumps with electrical and other mechanical drives
Progress continued on mechanised irrigation equipment, pumps for the chemical and petrochemical industries, whole pumping installations for power stations and finally, pumps for nuclear power stations
Today the famous Sigma K series hand pumps are affectionately referred to as "the world's most successful pump"
