Gear pumps are positive displacement pumps, available in a variety of designs, but there are two basic types: external and internal. External gear pumps consists of two identical, interlocking gears supported by separate shafts. Internal gear pumps have two interlocking gears of different sizes with one rotating inside the other.
‍

Typical applications include:
- Petroleum
- Water
- Resins and Polymers
- Fats and Oils

Pump & Machinery offer a wide range of gear pumps from a variety of manufacturers, we stock Tuthill pumps and parts.

• And almost every other pit, tank or hole in the ground slurry application

The PACKO GFP challenges the laws of physics!

It is a known problem with centrifugal pumps: as soon as the pumped liquid contains more than about 8 % gas, a gas bubble builds up in the eye of the impeller and the pump loses its capacity.

The Packo GFP pump outsmarts physics. By placing a liquid ring impeller behind the centrifugal impeller, any possible build-up of a gas bubble is nipped in the bud by simply sucking it away.

In this way, our GFP pump can easily pump liquids with up to 30 % gas content. Would you like to know more? contact our technical support team to discuss your application.

Grundfos offers a wide range of dosing pumps representing state-of-the-art technology.

Digital Dosing solutions (SMART Digital, DME, DDI) set new standards in liquid chemical handling and accuracy. The operator can easily install and set up the pump to discharge exactly the quantity of dosing liquid required for the process in a unique drive- and flow-control management concept. The setting of the pump is displayed in ml/h, l/h or gph, and the operation mode is easily identified by means of icons.

The DMH mechanical hydraulic dosing pump range is the preferred choice for industrial and complex tasks. The DMH range is a series of extremely strong, robust pumps for applications where a substantial dosing range and high-pressure capabilities are required
