Yamada Trial Pump Program

1" Porto Fluido

As bombas AODD da série Yamada® NDP-25 fornecem uma vazão máxima de 46,2 galões por minuto. As bombas estão disponíveis em alumínio, aço inoxidável (316), Kynar® (PVDF), acetal moído e construção em polipropileno.
Conceito de válvula de ar unificada - 2 conjuntos de válvula de ar de tamanho comum usados para bombas de 6 tamanhos, reduzindo a confusão e o inventário de peças

Válvula de ar verdadeiramente não lubrificada - a válvula de ar patenteada em todas as bombas da série NDP nunca requer lubrificação ou pré-embalagem

Não-Stalling - manobra 304SS não centrada, assistida por mola, que garante uma mudança positiva sempre

Testado para durar mais de 300 milhões de ciclos

Aides in long head dead application para uma inicialização confiável

O que separa a Yamada do resto da embalagem é a nossa tecnologia de válvula de ar. A Yamada usa uma válvula de ar principal totalmente não lubrificada e mecanismos pilotos independentes para controlar a lógica do ar.

À medida que o ar comprimido entra na bomba, ele é direcionado através da válvula de ar principal para um lado ou para o outro, dependendo da posição inicial da bobina c. Quando o ar entra na câmara, força o diafragma para fora. Este impulso externo força o líquido para fora da válvula de esfera de descarga e carrega a válvula de esfera de entrada oposta. À medida que o diafragma se desloca para fora, o diafragma conectado no lado oposto está puxando o diafragma para dentro.

Quando percorrer um curso completo, ele entrará em contato com a válvula piloto, pressionando-a e quebrando a vedação para abrir uma porta de escape.

A porta aberta permite que o ar comprimido para o escape do lado de trás da válvula de ar. A queda de pressão produz um deslocamento da válvula de ar principal. Este movimento simplesmente repete do outro lado.

The Yamada Advantage

Yamada Air Powered Double Diaphragm Pumps: Engineered for High Performance. Manufactured for Long Life.

Rugged, Bolted Construction

All Yamada pumps feature bolted construction, which eliminates leaks and simplifies post-maintenance reassembly. Bolted construction is superior to clamp band retainers, which frequently require frustrating, unnecessary leakage rebuilds from misalignment during reassembly.

Outside-Accessible Air Valve

Inspection or maintenance of every Yamada air valve may be performed without removing the pump from service. Outside accessible, making it easy to fix / inspect.

Unified Air Valve Concept

Common-size air valve assemblies reduce parts confusion and inventory.

Pilot Valve

Unique to the Yamada design is an individual modular pilot valve that actuates the air valve. It is depressed slightly by the inner center disk creating a pressure drop at one end of the air valve, allowing shifting to occur. It is maintenance free with no cumbersome snap rings or lubricated dynamic o-rings to replace or repair.

Patented Air Valve Technology

Incorporated in every Yamada Air Powered Double Diaphragm pump

Yamada air valve technology is the heart of the air-powered double diaphragm pump and determines reliability. Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry.
