Castle Pumps Ltd. products

The Raasm range of air operated diaphragm pumps are typically used for high flow short distance applications, suitable for pumping low viscosity oils and similar fluids. Ideal for transferring fluids containing suspended solids with a max. Diameter of 3 mm. These air operated pumps are suitable for both central fixed and mobile systems with a variety of suction tube lengths to suit drums from 180 to 220 kg. Also suitable for tanks installations where the drum pump is immersed. These barrel pumps are suitable for pumping the following fluids among others: Water, Mineral-Vegetable Oils, Diesel Oil, Windshield Washing Liquid and Antifreeze.

The Raasm Air Operated Grease Pumps are the ideal solution for the transferring of medium to high viscosity grease at high pressure over a long distance. This air operated pump`s double reciprocating action ensures a continuous flow at high pressures. Typically used as drum pumps, the Raasm grease pump range are suitable for both central fixed installations and mobile systems, available with differing lengths of riser tubes to suit drums from 16kg to 220kg. These barrel pumps can also be immersed within a tank.

The Debem Boxer Air Operated Diaphragm Pump is a versatile and modular air driven positive displacement pump, designed to be a cost effective and leak free. The Boxer AOD pump is available in a multitude of material and build specifications and sizes, enabling it to be suited to almost any application. The Debem Boxer air operated diaphragm pumps are suitable for demanding applications including highly humid environments and potentially explosive atmospheres. There are also food grade and sanitary versions of the Boxer AOD pumps for hygienic applications.

The Debem Cubic Air Operated Diaphragm Pump is a miniature and compact pump, designed for confined spaces where typical AOD pump cannot be used. This Debem range of AOD pumps benefit from high performance, power and sturdiness and are suitable for pumping fluids with high apparent viscosity, even in the presence of suspended solids. Due to their low flow rate range, the Cubic air operated diaphragm pumps are also ideal for small transfer and dosing applications.
