A \u003cb\u003e12 litre DURAMANT-coated steel tank\u003c\/b\u003e feeds a \u003cb\u003e45ml-per-stroke\u003c\/b\u003e piston pump through a \u003cb\u003esteel mesh–reinforced test hose\u003c\/b\u003e, while a \u003cb\u003edual-valve (Twin-Valve) mono-block design\u003c\/b\u003e lets you fine-tune pressure and self-test the pump's own seals without breaking the test circuit. A built-in \u003cb\u003edrag indicator\u003c\/b\u003e holds the peak pressure reached, making slow leaks easy to spot at a glance. Suited to boiler and pressure-vessel manufacture, solar thermal filling, and commercial heating circuits where the RP30's 30 bar range isn't enough.\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; margin: 0 -4px 28px -4px;\"\u003e\n\u003cdiv style=\"flex: 1 1 140px; background: #008377CF; color: #ffffff; padding: 16px 10px; border-radius: 8px; text-align: center; margin: 4px; min-width: 140px;\"\u003e\n\u003cdiv style=\"font-size: 20px; font-weight: bold; line-height: 1.2;\"\u003e60 bar\u003c\/div\u003e\n\u003cdiv style=\"font-size: 12px; font-weight: 400; opacity: 0.92; margin-top: 4px; letter-spacing: 0.3px;\"\u003eMax Test Pressure\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 140px; background: #008377CF; color: #ffffff; padding: 16px 10px; border-radius: 8px; text-align: center; margin: 4px; min-width: 140px;\"\u003e\n\u003cdiv style=\"font-size: 20px; font-weight: bold; line-height: 1.2;\"\u003e12L\u003c\/div\u003e\n\u003cdiv style=\"font-size: 12px; font-weight: 400; opacity: 0.92; margin-top: 4px; letter-spacing: 0.3px;\"\u003eTank Capacity\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 140px; background: #008377CF; color: #ffffff; padding: 16px 10px; border-radius: 8px; text-align: center; margin: 4px; min-width: 140px;\"\u003e\n\u003cdiv style=\"font-size: 20px; font-weight: bold; line-height: 1.2;\"\u003e45ml\u003c\/div\u003e\n\u003cdiv style=\"font-size: 12px; font-weight: 400; opacity: 0.92; margin-top: 4px; letter-spacing: 0.3px;\"\u003eDelivery Per Stroke\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 140px; background: #008377CF; color: #ffffff; padding: 16px 10px; border-radius: 8px; text-align: center; margin: 4px; min-width: 140px;\"\u003e\n\u003cdiv style=\"font-size: 20px; font-weight: bold; line-height: 1.2;\"\u003eR1\/2\" BSPT\u003c\/div\u003e\n\u003cdiv style=\"font-size: 12px; font-weight: 400; opacity: 0.92; margin-top: 4px; letter-spacing: 0.3px;\"\u003eConnection\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 140px; background: #008377CF; color: #ffffff; padding: 16px 10px; border-radius: 8px; text-align: center; margin: 4px; min-width: 140px;\"\u003e\n\u003cdiv style=\"font-size: 20px; font-weight: bold; line-height: 1.2;\"\u003e50°C\u003c\/div\u003e\n\u003cdiv style=\"font-size: 12px; font-weight: 400; opacity: 0.92; margin-top: 4px; letter-spacing: 0.3px;\"\u003eMax Working Temp\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 140px; background: #008377CF; color: #ffffff; padding: 16px 10px; border-radius: 8px; text-align: center; margin: 4px; min-width: 140px;\"\u003e\n\u003cdiv style=\"font-size: 20px; font-weight: bold; line-height: 1.2;\"\u003e8kg\u003c\/div\u003e\n\u003cdiv style=\"font-size: 12px; font-weight: 400; opacity: 0.92; margin-top: 4px; letter-spacing: 0.3px;\"\u003eNet Weight\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #FBEAE8; border-left: 4px solid #C0392B; padding: 14px 18px; border-radius: 4px; margin: 0 0 18px 0; color: #33403f; line-height: 1.55;\"\u003e\n\u003cdiv style=\"font-weight: bold; color: #c0392b; margin-bottom: 4px;\"\u003ePressure Safety\u003c\/div\u003e\n\u003cdiv\u003eNever exceed the \u003cb\u003e60 bar maximum test pressure\u003c\/b\u003e.
