The Elcometer KARA Double Diaphragm Transfer Pumps are air-operated 1:1 ratio pumps that supply water and solvent based materials smoothly and consistently to spray application points. Steady, pulse-free fluid delivery keeps paint homogenous and feeds the gun without surging, which is what prevents inconsistent film build and supports running long fluid hoses or multiple spray guns from a single source.

The range covers three models. The KARA 30 (PTD130AS) delivers up to 30 litres per minute maximum free flow and uses stainless steel seats and balls with a polyethylene diaphragm. The KARA 40 (PTD140AS) delivers up to 40 lpm with polypropylene seats, PTFE balls and a PTFE diaphragm for water based and solvent materials. The KARA 40A (PTD140AAS) is the abrasive version, fitted with stainless steel balls and seats to suit ceramic based materials. Construction across the range uses aluminium, stainless steel, PTFE and polyamide, with a lightweight anodised aluminium pump housing that is fast to service on site using standard tools.

The pumps handle a maximum fluid particle size of 0.25mm, a fluid temperature range of 4.4 to 60 degrees C, and 1/2 inch BSP male fluid inlet and outlet, with a low pulsing air distribution manifold using metal to metal technology to prevent stalling. The KARA 40 is also available with a 200 litre drum cover (PSD140AS-C) and rotary agitator (PSD140AS-C-RA). Supplied by BAMR, South Africa's authorised Elcometer distributor.
