JS GS Heavy-Duty Grinder Sewage Pumps Powerful Maceration for the Most Demanding Wastewater Systems
The JS GS Series (GS1200 & GS1500) represents the ultimate in heavy-duty sewage pumping, built specifically for severe-duty applications where solids, fibrous waste, and tough debris are a constant challenge. These grinder/macerator pumps are engineered to shred and grind waste into fine particles, making them ideal for use in sewage systems, pumping stations, industrial effluent handling, and agricultural waste management.
The GS-1200 and GS-1500 by JS are a range of heavy duty sewage grinder/sewage macerator single phase submersible pumps ideal for use where high heads or long distances prevent the use of standard submersible pumps.
They include a heavy duty construction suitable for grinding and pumping organic waste to the main sewage line or treatment plant and are ideal if only a small bore discharge pipe is available.
Grind It, Dont Just Pump It
Unlike standard sewage pumps, the GS Series features a hardened steel macerator blade that cuts, grinds, and pulverises solid matter before dischargeprotecting your pipework, reducing clogging, and maintaining flow efficiency.
Perfect for:
Industrial and commercial effluent treatment
Remote or off-grid sewage systems
Domestic properties prone to blockages
Pumping stations and sewage lift systems
Agricultural and livestock slurry transfer
GS Grinder pumps have tungsten carbide cutters and grinding rings which allow for up to 28,000 cuts per minute.
In addition, all of the GS1200 and G1500 sewage grinder pumps include double oil bathed mechanical seals for reliability and longevity. The GS range of sewage submersible macerator pumps are our toughest and most reliable choice for domestic and commercial sewage grinder applications.

Customer reviews
Good advice given over the telephone by the guys. Pump received next day as promised and working well. Thank u.
Thorntons Halt Camp Site | Notts | September 2018
Saved the day. Recently moved into a new house with a pump system installed. Current pump had failed and caused me and my wife no end of head aches trying to have it fixed by another company at great expense. I spoke to Henry Pumps who quickly ascertained that in actual fact it turned out to be the wrong type of pump installed as our pipework was too small. Henrys recommended this grinder pump. Installed and working a treat. Many thanks.
Mr. Patrick | Newark | September 2018
Ordered as a replacement for when our original pump failed. Arrived the next day as they said it would. Can't fault them.
Jay Dunn | Easingwold | September 2018
Purchased the GS1200 macerator pump on the advice of Henry Pumps. Really good choice as this has been pumping very well now for a good couple of months. Wouldn't hesitate to buy again from Henry Pumps.
