The Hashtek Gentle Hash Pump System is designed to move trichome-rich water through your hash lab when gravity draining is not practical. It is a great solution for labs with height limitations, multi-tank agitation setups, collection vessels, and workflows where wash water needs to be transferred efficiently between vessels.

This pump system is now available in three configurations: electric diaphragm, pneumatic diaphragm, and electric vortex.

Electric Diaphragm Pump
The electric diaphragm pump is a gentle plug-in option for moving trichome-rich water without needing compressed air. Diaphragm pumps move water using a pulsing membrane instead of a high-speed impeller, helping reduce the shearing forces that can damage delicate trichome heads before filtration. This is a strong choice for hashmakers who want gentle product handling with a simple electric setup.

Pneumatic Diaphragm Pump
The pneumatic diaphragm pump is the most traditional gentle hash pump option. It uses compressed air to power an air-operated double diaphragm pump, moving trichome-rich water with minimal mechanical shear. This option is ideal for commercial labs that already have compressed air available and want a durable, adjustable, and gentle pump system.

Hashtek pneumatic pump systems are properly built with air controls, including a pressure regulator, dial pressure gauge, shut-off valve, quick disconnect, and compressed air lubricator.

Electric Vortex Pump
The electric vortex pump is a centrifugal-style pump and the most cost-effective configuration. Centrifugal pumps move water using a spinning impeller, so they are not as gentle as diaphragm pumps in theory. That said, many Hashtek customers have had great success using vortex-style pumps in real ice water extraction workflows. This is a solid choice for customers who want an affordable, high-flow pump option.

Which pump should you choose?
For the gentlest handling of trichome heads, we recommend one of the diaphragm pump options. Choose the pneumatic diaphragm pump if your lab already has compressed air available. Choose the electric diaphragm pump if you want a simpler plug-in solution without an air compressor.

Choose the electric vortex pump if budget is the main priority and you want a proven, affordable centrifugal pump option that many hashmakers have successfully used.

The Hashtek Gentle Hash Pump System is especially useful for labs that cannot rely on gravity drains, operators running multiple wash tanks, or anyone looking to streamline water transfers between agitation tanks, collection vessels, and filtration setups.
