The Houttuin range of heavy duty twin screw pumps (two-spindle screw pumps) offer reliable pumping for demanding applications. Twin screw pumps are a standout for applications in the Oil, Gas, Power and Shipping industries. Houttuin have been perfecting the twin screw pumps since the early 1900’s when young engineer Cees Houttuin developed and built his first twin screw pump for a Dutch coal mine.
Houttuin twin-geared screw pumps are manufactured in small standard series or tailor-made. The standard pumps are divided into four product groups.
100 series:
Horizontal single entry twin-screw pumps for low range pressures (max. 10 bar) and limited capacities of aggressive chemical liquids.
200 series:
Horizontal and vertical double entry twin-screw pumps, covering a flow range up to 2500 m3/hr at a maximum pressure of 25 bar.
211/215 series:
Vertical double entry twin screw pumps for lubricating (generally maritime) purposes in limited space.
Engineered series 200/300:
Horizontal twin screw pumps, each pump being a one-off piece or part of a small series, designed and constructed according to customer specifications on, for instance, high and low viscosities, large capacities and high pressures (up to 80 bar). In addition to standard pumps, the company specializes in tailor-made solutions which meet the specific demands of each branch of industry.
