Filter Press Feed Pumps

Latham International Ram pumps

This is a ram type reciprocating piston pump that is driven by a separate electrically powered hydraulic power unit.

The pump and hydraulic power unit form a single integrated pump set.

The pump is of robust, heavy-duty design and construction with an anticipated working life well in excess of 20 years. The pump body and the valve boxes are one piece steel fabrications. The sludge ram is manufactured from stainless steel. The sludge seals are maintenance free chevron rings, which are replaceable as a service item without the removal of the sludge ram.

Model 160 Ramp Pump - Stainless Steel

Range (Ram Size)

You can download our pump brochure by clicking here for the English version or click here for the Spanish version.

The hydraulic cylinder driving the sludge ram is built to off shore specifications and is of a hardwearing design featuring a chrome piston rod. The hydraulic cylinder also features extensive internal guidance and support for the piston rod thereby eliminating lateral forces upon the hydraulic seals, which can promote oil leaks. The top of the hydraulic cylinder features internal, hydraulic cushioning to facilitate absolute control over the sludge ram at the top of the stroke where the ram changes direction from up to down. This contributes to the quite operation of the pump.

This hydraulic unit comprises a hydraulic oil tank beneath which sits an electric motor driving through a bell housing and coupling to a variable speed, pressure compensated hydraulic oil pump.

Refurbished Willett Pumps and Willett Pump Spare Parts

Refurbished 6 inch Willett Pumps

We are able to offer refurbished Willett Pumps and Willett Pump Spares, including

Willett Pump Spares

We stock an extensive range of consumable replacement parts for various types and sizes of ram pumps, including:

Test Work

In House and Site Filtration Evaluation Trials.

Latham International have facilities for filtration trials both in house and on site.

In house via our laboratory utilising pilot size equipment allowing basic trials to be carried out on small sample volumes.

On Site via our trailer mounted self contained test rig that requires no additional incoming services other than the material to be filtered.

Our mobile rigs allow for both conventional and membrane filtration up to 20 bar, along with inbuilt facilities for both cake washing and air blowing if required.
